A controlled reader renders accepted application frames in a new
virtual-only cthulhu-braille mode at the controller's width and applies
its pan and route gestures; reader UI, flashes and secure frames are
never exported, and hidden frames are unroutable. A controller reader
reports its display width, shows peer cells as an untranslated raw
frame and forwards local pan and routing keys. The physical helper now
reports its width and edge pans.

Keep failed cursor trials and native recapture anchored to the original document, and restore the requested cached root before LRU eviction. Base braille retry resets on established connection time rather than stalled startup. Poll private AT-SPI daemon ownership without triggering service activation and clean up partial startup failures. Add focused regressions and update browser testing notes.
Helper retries BrlAPI open in-process until BRLTTY answers, supervisor waits with the parked helper instead of kill/respawn cycles, exponential backoff and warn-once for real helper exits, bounded give-up so permanent failures still surface.
