v0.16.0

Dashboard Verbose Activity View

Per-member activity timeline in the dashboard drawer showing tool calls, shell commands, step transitions, reasoning blocks, file diffs, and prompts/responses — with a verbose toggle for full detail.

• ActivityBuffer — in-memory rolling buffer (100 entries/session) capturing real-time v2 events
• /api/session/:sessionId/activity endpoint — combines buffered data with session.messages() fallback
• Reasoning blocks — model chain-of-thought in collapsible violet-tinted panels
• File parts — file paths and content/diffs in collapsible cyan-tinted code blocks
• Text entries — prompts and responses rendered with markdown, colored by role
• Structured tool I/O — tool input/output JSON-formatted when objects
• Verbose toggle — compact (brief labels only) vs verbose (full titles + detail blocks + cost/tokens)
• localStorage persistence — verbose preference survives page reloads
• v keyboard shortcut — quick toggle for verbose mode
• Extracted recordFromV2Event, recordFromToolBefore, recordFromToolAfter into exported functions
• Race guard on fetchActivity to prevent stale fetch overwrite
• Activity buffer cleanup on team_cleanup
• URL-encoded session ID decoding in activity route
• Sorted combined activity entries by timestamp
