fix(ui): address PR #52 review — 10 items across Hoshe, Tyre, Araminta (#535)

Critical: bump PROTOCOL_VERSION 8→9 for conversation_events/ended fields.

Hoshe review:
- Dirty flag (_log_dirty) prevents per-frame O(n) BBCode rebuild
- BBCode injection: _escape_bbcode() replaces [ with [lb] on server text
- D-064 regression: dialogue_active cleared in fade callback, not before
- YAML quoting: remove unnecessary quotes from numeric values

Tyre review:
- Carry-forward for dialogue_response, conversation_events, conversation_ended
  in receive_bytes() — arrays merge, scalar falls through
- pause_requested/unpause_requested signals route through main.gd input
  recording (_pending_record_inputs) for #507 replay determinism
- Fix version comments: dialogue_response is v8 (#305), not v9
- Remove dead _active_overheard dictionary

Araminta review:
- Passive lines: ┃ glyph prefix + _desaturate() for name colours
- Active conversation entries pinned (no timeout), unpinned with timestamp
  reset on conversation end
- _enforce_contrast(): minimum luminance floor for name colour readability
- Simplified 1-on-1 attribution: "Speaker:" instead of "Speaker → You:"
