azos-core bump: fix over-eager AZOS_AGENT_SHELL_SESSION guard on SessionStart hook

Mirrors the azos-core change: azos.claude.enable now sets
azos.agent-memory.backends.claude.enable and
azos.agent-skills.backends.claude.enable instead of the old
azos.claude-memory.enable/azos.claude-skills.enable. The new agent-shell
memory backend needs no wiring here -- it's bundled directly in
azos-core's editor/emacs module, alongside wherever agent-shell itself
gets installed.

+Features are auto-discovered by `import-tree` — no central imports file. Each feature's
+`default.nix` registers itself via `config.flake.modules.homeManager.<name>`. Modules are
+then explicitly imported in `home-manager/home.nix` via `suiteModules.homeManager.<name>`.
+
+**Where to put a new feature:**
+- Shared / reusable across machines → inside an existing or new suite directory,
+  `azos-core/suites/<suite>/<name>/default.nix` (registering
+  `config.flake.modules.homeManager.<suite>`) — never a bare file directly under
+  `azos-core/suites/`; every azos-core feature belongs to a suite.
+- Machine-specific → `azos/features/<name>/default.nix`
+
+## Code Style Guidelines
 
 ### Nix Module Template
 
-```nix
+All features follow this flake-parts registration pattern:
-{
-  lib,
-  config,
-  pkgs,
-  ...
-}: let
-  isEnabled =
-    config.azos.<module-name>.enable;
-in {
-  options.azos.<module-name>.enable = lib.mkOption {
-    default = true;
-    example = true;
-    type = lib.types.bool;
-  };
 
-  config = lib.mkIf isEnabled {
+```nix
-    home.packages = with pkgs; [ pkg1 pkg2 ];
+{...}: {
+  config.flake.modules.homeManager.<name> = {
+    lib,
+    config,
+    pkgs,
+    ...
+  }: {
+    options.azos.<name>.enable = lib.mkOption {
+      default = false;
+      example = true;
+      type = lib.types.bool;
+    };
+
+    config = lib.mkIf config.azos.<name>.enable {
+      home.packages = with pkgs; [pkg1 pkg2];
+    };
   };
 }
 ```
 
 ### Naming Conventions
-- Option paths: `config.azos.<module-name>.<option>`
+- Option paths: `azos.<module-name>.<option>`
-- Enable option: `enable` (bool), default `true`
+- Module names: kebab-case (`git-config`, `desktop`)
-- Module names: kebab-case (`libreoffice.nix`, `git-config.nix`)
+- Feature directories: kebab-case, one `default.nix` per feature
-- Option names: may differ from filename (e.g., `git.nix` uses `azos.git-config`)
+- Variables: kebab-case
-- Variables: kebab-case (`isEnabled`)
 
 ### Formatting
 - Indentation: 2 spaces
-- Let bindings: multi-line with `isEnabled` on its own line
+- Packages: `with pkgs; [pkg1 pkg2]` (no trailing semicolon inside list)
-- Packages: Use `with pkgs; [ ... ]` syntax
 
 ### Imports
-- Always include `{...}` for module args
+- Always include `{...}` for the outer module args
-- Standard args: `lib, config, pkgs, ...`
+- Inner module args: `lib, config, pkgs, ...`
-- NixOS config args: `inputs, outputs, lib, config, pkgs, ...`
-- Use `./relative/path.nix` for local imports
 
 ### Option Patterns
-- Boolean enable: `lib.mkOption { default = true; example = true; type = lib.types.bool; }`
+- Boolean enable: `lib.mkOption { default = false; example = true; type = lib.types.bool; }`
-- Conditional config: `lib.mkIf isEnabled { ... }`
+- Conditional config: `lib.mkIf config.azos.<name>.enable { ... }`
-- User-overridable: `lib.mkDefault`
+- Auto-enable a dependency: `azos.<dep>.enable = lib.mkDefault true;`
 - Force value: `lib.mkForce` (sparingly)
 
+### Extensible Options
+For options that multiple modules should be able to contribute to, use attrset options:
+
+```nix
+options.azos.<name>.things = lib.mkOption {
+  default = {};
+  type = lib.types.attrsOf lib.types.path;  # or lines, str, etc.
+};
+```
+
+Any module can then add entries without modifying the owning feature. Examples in use:
+- `azos.claude.globalSkills` — attrset of skill name → markdown file path
+- `azos.claude.globalMdSections` — attrset of key → markdown string (merged into `~/.claude/CLAUDE.md`)
+
 ### Home-Manager vs NixOS
 - Home-manager: `home.packages`, `home.file`, `programs.<program>`
 - NixOS: `config.services`, `environment.systemPackages`
 
+### Deploying Files
+- Static file: `home.file."dest".source = ./file;`
+- Generated text: `home.file."dest".text = "...";`
+- Runtime script (e.g. merging JSON at activation): `home.activation.<name> = lib.hm.dag.entryAfter ["writeBoundary"] ''...'';`
+
 ### Suites System
-Modules are organized into suites (defined in `azos-core/`):
+Top-level suites group related features (defined in `azos-core/`):
-- `azos.suites.base` - Base packages and config
+- `azos.suites.base` — base packages and config
-- `azos.suites.editor` - Editor tools
+- `azos.suites.editor` — editor tools
-- `azos.suites.dev` - Development tools
+- `azos.suites.dev` — development tools
-- `azos.suites.station` - Desktop applications
+- `azos.suites.desktop` — desktop session plumbing (flameshot, dunst, keyboard layout) plus generally-useful apps (browser, libreoffice, zoom, spotify, gimp, whatsapp). Shared, lives in azos-core — wanted on any GUI machine, work included.
-- `azos.suites.exwm` - EXWM window manager
+- `azos.suites.exwm` — EXWM window manager, depends on `desktop`
-- Enable in `home-manager/home.nix` with `azos.suites.<name>.enable = true;`
+
+Machine-specific, personal-only apps (steam, discord) are **not** part of any azos-core
+suite — they live as standalone features directly in `azos/features/`, imported only on
+machines that want them (e.g. `azos/features/discord`, `azos/features/steam`), since any
+such machine already uses the `azos` project rather than a different downstream repo.
+
+The machine suite (`azos.suites.lauretta`) enables the relevant suites for this machine.

+## Agent Memory/Skills Integration
+
+Memory (org-roam) and skills (slash commands/CLAUDE.md) are backend-pluggable, not
+Claude-specific, even though Claude is currently the only skills backend and one of two
+memory backends:
+
+| Feature | Option | What it does |
+|---------|--------|--------------|
+| `azos-core/suites/base/agent-memory` | `azos.agent-memory.backends.claude.enable` | Registers org-roam-mcp as a global MCP server in `~/.claude.json`; hooks resync org-roam's index on edit and inject project context at session start |
+| `azos-core/suites/base/agent-memory` | `azos.agent-memory.backends.agent-shell.enable` | Registers org-roam-mcp via `agent-shell-mcp-servers` and resyncs on `file-write` events — applies regardless of which ACP backend (Claude, Gemini CLI, Codex, ...) a given agent-shell session runs. Also marks Claude sessions agent-shell launches (`AZOS_AGENT_SHELL_SESSION=1`) so the claude backend's own hooks no-op for those sessions instead of double-acting |
+| `azos-core/suites/base/agent-skills` | `azos.agent-skills.backends.claude.enable` | Deploys skills to `~/.claude/commands/` and content to `~/.claude/CLAUDE.md` |
+| `azos/features/claude` | `azos.claude.enable` | Installs claude-code, auto-enables the claude backend for both of the above |
+| `azos-core/suites/editor/emacs` | (bundled, not a separate option) | Installs agent-shell, auto-enables `azos.agent-memory.backends.agent-shell.enable` |
+
+Both agent-memory and agent-skills register `config.flake.modules.homeManager.base`
+(they live inside the `base` suite, since that's where agent-shell is introduced) — not
+standalone module names, so no separate `suiteModules.homeManager.*` import is needed for
+them in `home-manager/home.nix`.
+
+### Adding Claude skills or standing instructions
+From any module — no need to touch azos-core:
+```nix
+azos.claude.globalSkills.my-skill = ./skills/my-skill.md;
+azos.claude.globalMdSections.my-rule = ''
+  # My Rule
+  Always do X when Y.
+'';
+```
+`globalSkills`/`globalMdSections` stay Claude-specific (`~/.claude/commands/`,
+`~/.claude/CLAUDE.md`) deliberately — no other backend has a uniform equivalent yet. See
+`azos-core/suites/base/agent-skills/README.md` for full documentation.

+** Elfeed Nextcloud News Sync
+
+[[https://github.com/fasheng/elfeed-protocol][elfeed-protocol]] adds an =owncloud+= protocol that speaks the
+ownCloud News API, which the Nextcloud News app also implements, so
+it syncs elfeed's feed list and read/unread state with the Nextcloud
+News app instead of just reading a local feed list one-way.
+
+Reuses the same =zakobar.com= pass entry as the CalDAV sync above,
+since it's the same Nextcloud account.
+
+As of elfeed-protocol 1.0.0 (paired with elfeed >= 4.0.0), the
+credentials go directly on =elfeed-feeds= — the older
+=elfeed-protocol-feeds= variable is dead: setting it only logs a
+deprecation warning, and =elfeed-feeds= ends up with the bare URL
+and no =:password=, so requests silently authenticate with an empty
+password and nothing ever lands in the db.
+
+Fetching the password with =shell-command-to-string= used to
+deadlock Emacs whenever the GPG PIN cache had expired: that call
+blocks Emacs's single thread on the =pass|gpg= subprocess, but
+=pinentry-emacs= (see the GPG Pinentry section above) needs Emacs's
+command loop running to answer its loopback prompt — so Emacs waits
+on gpg-agent while gpg-agent waits on Emacs. Fetching the password
+with =make-process= instead keeps the command loop alive, so
+=pinentry-emacs= can prompt normally; =elfeed-feeds= and
+=elfeed-protocol-enable= are only set once the process sentinel
+fires. Same stderr-redirect reasoning as before, to keep a stray
+gpg/pass warning off the captured password.
+
+The fetch is wrapped in a named, interactive function rather than
+inlined in =:config= so a failed attempt (e.g. =pass= produced no
+output because the YubiKey wasn't plugged in yet) can be retried
+with =M-x azos/elfeed-protocol-init-feeds= — re-running =:config=
+itself would require reloading the =elfeed-protocol= feature
+entirely. An earlier version passed =(process-get proc 'output)=
+straight to =string-trim=, which signals (not just returns nil) when
+no output was ever read, aborting the sentinel before =elfeed-feeds=
+or =elfeed-protocol-enable= ran — so a failed first attempt left
+=elfeed-feeds= permanently =nil= for the rest of the session with no
+visible error beyond a =*Messages*= line, and every subsequent
+=elfeed-update= silently had nothing to fetch.

+** Elfeed Full Article Fetch
+
+Many feeds only publish a short excerpt. elfeed >= 4.0 has built-in
+commands for this — =f= (=elfeed-show-fetch-link=) fetches the
+linked page and appends it to the show buffer, =R=
+(=elfeed-show-readable=) strips the fetched page down to
+article text via eww's readability scorer — and both can run
+automatically via =elfeed-show-update-hook=, gated on a feed's
+=:fetch-link=/=:readable= metadata.
+
+That gating keys off an exact match on the feed's URL/id in
+=elfeed-feeds=, which breaks for ownCloud/Nextcloud subfeeds:
+elfeed-protocol synthesizes a per-subfeed id of the form
+=<host-url>::<subfeed-url>= that never appears in =elfeed-feeds=
+(only the bare host URL does), so the metadata lookup always misses
+and the stock hooks never fire. Replacing them with unconditional

+=lichess.org= in pass already holds the website login password, and

+Store it separately under =lichess.org/token= (=pass insert
+lichess.org/token=) and set the =lichess-token= variable directly —
+=lichess-token= (the function) checks this variable before falling
+back to =auth-source=, so this takes precedence without disturbing
+the existing =lichess.org= entry or its consumers (e.g. browserpass).
+
+=shell-command-to-string= merges stderr into its return value, so any
+gpg/pass warning on stderr (e.g. an unsafe-permissions notice) would
+otherwise get concatenated onto the token and break auth silently.
