Desktop chat message queue (v0.5.2):
- Queue follow-up messages (Enter) while the agent is busy; FIFO auto-drain
on true idle. Collapsible, height-capped to-do panel above the composer so
it never inflates the composer. Per-item move-to-top/edit/delete/clear.
Never drains mid-stream, during tool execution, or while a permission
prompt is pending; Stop cancels the current turn but keeps the queue.
Per-session isolation. In-memory only (no persistence schema change).
Also included in this commit:
- Settings provider form: model-id comboboxes + fetch-models + per-slot
context-window auto-fill.
- Bundled skills: defineGoal, pdf, screenshot.
- Bump desktop app to 0.5.2 with release notes.
Tested: desktop tsc --noEmit; Vitest chatStore/pages/ActiveSession 136 passed
(incl. 7 queue tests); browser end-to-end queue smoke; Windows x64 NSIS
package + package-smoke PASS.
Not-tested: full check:desktop suite has pre-existing unrelated failures
(electron packaging, theme cycling, ThinkingBlock label); check:server.
Scope-risk: moderate
Confidence: medium
