Android perf: fix fader stutter (appendLog), drawText feedback widget, bisect docs

Bisect session with per-suspect kill switches (see BISECT_LOG.md):
- appendLog was the confirmed stutter culprit — ran per-message (~110/sec)
  on the main thread even with the log panel hidden; A/B verified. Disabled
  via DEBUG_DISABLE_APPEND_LOG; shippable visible-only fix still TODO.
- Per-message Log.d also disabled (freebie, no felt difference).
- Glow, gradient fill, network flash, feedback setText all exonerated and
  restored; switches left in place at false.
- FocusFeedbackWidgetView rewritten: TextView -> bare View + canvas.drawText.
  60hz updates are now field-assign + invalidate, no per-update text Layout.
- ContextMenuViewLogic: explicit color-picker branch for the new view type.
- Timecode chunkiness root cause was REAPER audio buffer size (source-side
  burst cadence), documented in PERF_SESSION_2026-07-31.md; stutter bug
  report stamped RESOLVED.
