Download Control4 Drivers

Complete rebuild, solving all known issues currently reported.  

Note: if you are coming from a previous version, a full deletion of your controllers in Composer is necessary.

 - Added RequestDALIDownToOff wrapper in lib/tpi_client.lua, DOWN_TO_OFF IDC enum, dispatch + fire-and-forget allow-list entry in
 zc_lcm_driver/lcm_tpi.lua, name map in driver_names.lua, and a busted test verifying the on-the-wire byte layout.

 - Absolute input driver refactored to group instances by DALI address — a single driver now represents all absolute input instances on a
  DALI address instead of one driver per instance. Adds dynamic BUTTON_LINK bindings per instance, a "Number of Inputs" property,
 per-instance programming events, and a LAST_INPUT_CHANGED variable.

 - Min/Max DALI Level and Colour Temperature properties are now read-only — these values are read from the zencontrol system and should
 be changed there, not in Composer.

 - Long press stopped after ~3 dim steps — removed the 500ms auto-stop timeout that prematurely killed the repeat timer. DO_RELEASE is
 now the sole stop mechanism.
 - Direction did not flip on release — the auto-stop timeout and DO_RELEASE were both flipping direction, cancelling each other out. Now
 only DO_RELEASE flips.
 - Short press also triggered dimming — increased debounce from 50ms to 400ms so DO_CLICK has time to arrive before the handler assumes a
  long press. Short and long press are now cleanly separated.
 - Same fixes applied to TC Toggle and RGBWAF Toggle handlers.

 - C4 native keypads can now dim zencontrol lights via BUTTON_LINK bindings.
 - zencontrol keypads now work correctly with C4 native dimmers.
 - DimToggle, TC Cooler/Warmer/Toggle, and RGBWAF Up/Down/Toggle handlers now drive their own 200ms repeating timers internally instead
 of relying on repeated DO_PUSH events.

 - Added 6 BUTTON_LINK bindings to the blind driver: Open, Close, Stop, Toggle, Up, Down.
 - Keypads (C4 native or zencontrol) can now control blinds via the Composer Connections tab.
 - Toggle behavior: if any amount open, closes; if fully closed, opens.

 - Group controllers not re-commissioned after device deletion — fixed stale group driver rescan issue where group controllers were not
 properly re-commissioned when devices were deleted from a group.
 - ALS scene content not populated during creation — fixed issue where Advanced Lighting Scene content was empty when scenes were first
 created.

 - Absolute input driver added to release — the absolute input driver (Part 302 devices: potentiometers, sliders, rotary encoders) is now
  included in release builds.
 - Reduced group discovery log noise.

 - Device Name property — all drivers now expose a read-only Device Name property showing the full unfiltered reference name.
 - Group Controller fix — resolved Group Controller commissioning issues.
 - Blind driver improvements — various improvements to the blind driver.

 - Comprehensive documentation update for all drivers.
 - ECG driver documentation updated with naming conventions, actions, and auto-conversion details.

 - Auto-conversion table — native driver improvements with automatic device type conversion.
 - Switch events — push button event handling improvements.
 - Device type name visibility toggle — new option to show/hide device type suffix in device names.
 - Broadcast handling fix — fixed broadcast parameter handling for system-wide commands.

 - Dynamic BUTTON_LINK bindings based on actual scenes.
 - "Group Controller" suffix appended to DALI Group device names.
 - Scene sync — adds, renames, and removes scene bindings and ALS scenes.
 - Scene removal sync — deleted scenes are removed from C4 proxy and ALS agent on sync.
 - Flush stale scene state at start of each sync cycle.
 - Info-level logging for QUERY_SCENE_NUMBERS_FOR_GROUP.
 - TPI: stop retracting sequence number hint on request removal.
 - Enhanced BUTTON_LINK binding support across drivers.

 - Per-group scene controllers — one scene controller per group with per-group scene queries (replaces the previous single-controller
 approach).

 - Persistence preservation across driver updates — drivers preserve persistence data during updates and restore target_address from C4
 properties when persistence is lost.
 - ECG re-commission — removed device_driver_ids filter from all_ids_fn so devices can be re-commissioned.
 - Native relay/gate cross-branch sync — fixed sync issues plus several pre-existing bugs.
 - Fan double TPI commands — removed duplicate commands, fixed ON preset being ignored, added re-entry guard to FanState, deduped
 SET_SPEED proxy echo.
 - Commission guard — prevent duplicate device creation when sync runs concurrently.
 - LCM concurrency guards — added to commission and sync handlers.
 - Native manager — deep-copy ECG objects to prevent mutation corruption.
 - Sync cleanup — clean up device_driver_ids when a device is removed from Composer.
 - Discovery filter — filter already-commissioned devices from all_ids_fn.
 - Prototype table sharing — initialize table fields per-instance in all data-type constructors (fixes shared-state bug).
 - Keypad events — rewrite events with 1-based Switch naming, fix Composer overflow.

 - Group discovery — remove reply_type guard that blocked group commissioning (#52).
