Thread archiving support #10
Description
Summary
Add thread archiving as a distinct action from deletion. Currently, threads can only be hard-deleted via deletedAt. An archive mechanism would allow users to hide threads from the sidebar without permanently removing them.
Acceptance criteria
- Archive/unarchive action in thread context menu
- Archived threads hidden from sidebar by default
- "Show archived threads" toggle in sidebar
- Data model distinguishes archived vs. deleted (e.g.
archivedAttimestamp) - Backend WebSocket command support for archive/unarchive
Context
From TODO.md — "Thread archiving". Triaged as deferred (not release-blocking for v0.0.2).
