v0.9.0

New

• Project-grouped session tree — Sessions are now grouped under their project (project name + path at the top). Session rows show short ID + first user prompt instead of redundant project name.
• agenthud summary command — Generate LLM summary of daily activity via claude -p. Cached at ~/.agenthud/summaries/YYYY-MM-DD.md. Options: --date, --prompt, --force. Editable prompt template at ~/.agenthud/summary-prompt.md.
• In-app help (? key) — Full-screen help overlay listing all shortcuts, CLI commands, and file locations.
• Activity filter (f key) — Cycle through filter presets (configurable in config.yaml).
• Git commits in viewer + report — ◆ commit entries appear in the activity timeline. --with-git flag for report. Press ↵ on a commit to see git show --stat.
• agenthud report formats — --format json for machine-readable output, --detail-limit N for truncation control.
• hiddenProjects config — Hide entire projects from the tree via h key.
• Cold projects collapse — Projects where all sessions are cold collapse into a single ... N cold projects row at the bottom.
• Non-interactive sessions visualized — Sessions from claude -p / SDK shown in parens and dimmed.
• CLAUDE_PROJECTS_DIR env var — Override the Claude projects directory.

Changed

• Config / state split — ~/.agenthud/config.yaml holds user settings; ~/.agenthud/state.yaml holds app-managed hidden items. Auto-migrates on first run.
• Cold sessions and projects default collapsed — Inverse expansion: alive items default expanded (Enter collapses), cold items default collapsed (Enter expands).
• agenthud summary runs from ~/.agenthud/ — Avoids polluting user's working project with summary session files.
• Newlines preserved in detail view — Multi-line responses/thinking/prompts display with proper line breaks (previously flattened to single line).
• Viewer cursor/scroll preserved on refresh — fs.watch updates no longer reset the viewer position.
• g/G keys swapped — g = live (newest, top), G = oldest (bottom) — matches vim visual convention.
• getDisplayWidth cached — ~17% CPU reduction by memoizing repeated stringWidth calls.

Fixed

• Memory leak — NODE_ENV=production by default to stop React dev-mode profiler accumulating PerformanceMeasure objects (~600KB/s leak → ~50KB/s).
• Git access via --git-dir — Only .git needs to be accessible (works with mounted backups).
• Sub-agent navigation snap — Arrow keys recover gracefully when sub-agent disappears from flat list.
• Time displayed in local timezone — Report and viewer use local time instead of UTC.
• Ctrl+F no longer triggers filter — f key only fires without Ctrl modifier.
