fix(client): address PR #24 review — 5 critical bugs, 3 warnings, 8 suggestions

Critical:
- Protocol test assertions updated v6→v7 (test_protocol_v6.gd)
- Dialogue signal connections wired (option_selected→DialogueResponse,
  dialogue_dismissed→DialogueEnd sent to server via SimBridge)
- Consume-once race fixed: _consume_dialogue() checks is_dialogue_active()
  before re-showing; dialogue_id tracking prevents re-trigger during fade
- Dialogue box responsive: _update_layout() clamps width to MAX_WIDTH_PX
  (832px) or 65% viewport, height to 20% viewport (MAX_HEIGHT_RATIO)
- Auto-pause added: SimBridge.send_input(PAUSE) on dialogue open/close

Warnings:
- Test coverage: 16 new tests in test_protocol_v7.gd (pending_recognitions
  decode, current_dialogue, GameState, SimBridge mock data, insert colors)
- queue_redraw() optimization: early return when no entities and no pings
- Fixed 200px height → responsive 20% viewport via _update_layout()

Suggestions:
- WASD detection refactored to _WALK_AWAY_ACTIONS array loop
- Button colors reference Constants.INSERT_COLOR_TEXT/HOVER/ACTIVE
- Named constants: COLOR_TRANSITION_START, SILHOUETTE_APPEAR_THRESHOLD,
  SILHOUETTE_SIZE with explanatory comments
- Bounds check: MAX_PENDING_RECOGNITIONS=64 with truncation warning
- Mock dialogue sustained across ticks (not 1-tick flash)
- COLOR_PING coupling with cursor documented as intentional
- Consume helpers extracted: _consume_monologue(), _consume_dialogue()
