/perf-debug

Capture and analyze performance diagnostics from the running Android app.

Steps: 1. Clear logcat and start background capture with `adb logcat -c && adb logcat > /tmp/zedra-perf-capture.log &` 2. Tell the user: "Logcat capture started. Interact with the app on your device — navigate screens, open files, scroll, use the terminal, open/close the drawer. Say **done** when finished." 3. Wait for the user to say "done" 4. Stop the background logcat capture 5. Run `./scripts/perf-debug.sh` with the captured log, or run it directly (it handles its own capture) 6. Read the output and present a categorized summary:

• **Renderer**: frame timing stats from `[gpui_wgpu]` lines
• **Navigation**: screen transitions, file loads
• **Editor**: cache rebuild frequency and size
• **Terminal**: data processing events
• **Touch**: fling start/end counts, drawer snap events
• **Transport**: connection type changes, reconnect attempts
• **File Explorer**: entry count changes
• **Errors**: any panics, crashes, or ANRs
• **Memory**: RSS from dumpsys

7. Highlight any anomalies (frame times >16ms, excessive cache rebuilds, errors)
