Implements the full AI-Enhanced Dialogue feature for Sprint 26:
- HardwareDetector autoload (extends Node): three-layer detection —
Layer 1 RAM classification (pass/marginal/fail, thresholds 2GB/1.6GB),
Layer 2 TPT benchmark cache (green/yellow/red, thresholds 6/3 t/s),
Layer 3 degradation monitoring (>40% drop → yellow). load_ai_pref()
restores toggle state from user://settings.cfg on startup.
- Settings dialog AI section: toggle, colored status dot, status message
label, testable API (get_ai_dialogue_label_text, set_ai_dialogue_
hardware_status, is_ai_dialogue_toggle_enabled). Only RAM "fail" greys
out toggle — player always overrides yellow/red recommendations (D-138).
- GameState.ai_enhanced_dialogue_enabled (default true, opt-out model).
GameState.settings_response (v20 one-shot settings dump from server).
apply_snapshot() hydrates ai_enhanced_dialogue_enabled from full dump.
- Protocol v19→v20, settings_response decoding in decode_snapshot().
Protocol converted to extends Node autoload (enables test has_method).
encode_change_settings() helper for test inspection.
- InputMapper: CHANGE_SETTINGS, REQUEST_ALL_SETTINGS, DELETE_SETTING.
SimBridge: wire mappings for all three. RequestAllSettings queued after
handshake to hydrate client state from server SQLite on connect.
settings_response carry-forward in receive_bytes().
