v0.8.4

New

• Git commits in viewer — ◆ commit entries appear in the activity timeline (session date range, refreshed every 30s)
• Git commits in report — --with-git merges commits into the timeline chronologically
• Detail view for commits — Press ↵ on a commit to see git show --stat
• Activity filter — Press f to cycle through filter presets (configurable in ~/.agenthud/config.yaml)
• --detail-limit — Control truncation in agenthud report (0 = unlimited)
• --format json — JSON output with sub-agents nested under parent sessions

Fixed

• g/G keys swapped — g now goes to live (newest), G goes to oldest, matching visual vim convention
• Filter resets scroll — Applying a filter no longer leaves the viewport pointing outside the results
• Git date range — Viewer fetches commits across the full session date range, not just today
• Ctrl+F no longer triggers filter — f key only fires without Ctrl
• Sub-agent navigation snap — Arrow keys no longer jump to first session when sub-agent disappears from flat list
• Sentinel expansion — Expanding __sub-parent__ sentinel now moves selection to first newly-visible sub-agent
