v0.3.0: Conversation Intelligence & Burst UI Coalescing

Added

• Conversation-Aware Focus & Identity:
  • Conversation-aware identity and transcript parsing (BrainTranscriptParser) mapping agent events directly to specific conversation threads.
  • Exact focus restoration semantics prioritizing active conversation workspaces.
• Storage Engine v2:
  • SQLite Schema v2 introducing conversation_id, conversation_title, and metadata_json with automated migration runner and rollback safety.
  • Hardened WAL recovery preserving journals during degraded mode.
• UI Event Coalescing:
  • High-frequency event burst coalescer (UIEventCoalescer) throttling up to 1,000 multi-agent events into single bounded UI passes with 99.9% dispatch reduction.

Changed

• Hardened process execution runner (AsyncProcessRunner) with non-blocking stream handling to prevent deadlock on large pipe buffers (>100KB).

Fixed

• Resolved multi-turn session reactivation and stale discovery protection.
• Addressed architectural findings F-01 through F-13.
