- Auto-rebuild knowledge/index.md from the real directory tree on
create/import so it never drifts or loses documents (no longer relies
on the agent hand-writing it).
- Auto-open the created/imported document in the tree after success.
- Add create_document status message, shorten EN action buttons, and
localize the "insert template" content.
- Show filename for protected system files (index.md/log.md) in the tree
instead of their H1 heading.
- Reuse a shared embedding-provider factory so knowledge index sync also
gets vectors instead of degrading to keyword-only search.
- Use LLM to summarize discarded context into concise daily memory entries
- Batch trim to half when exceeding max_turns/max_tokens, reducing flush frequency
- Run summarization asynchronously in background thread, no blocking on replies
- Add daily scheduled flush (23:55) as fallback for low-activity days
- Sync trimmed messages back to agent to keep context state consistent
