Create hal-device module, fix GPIO, fix tests, fix TactilityC (#471)

* **New Features**
  * Added a HAL device module providing device enumeration, type queries and a HAL↔kernel bridge.

* **Improvements**
  * Integrated HAL module into startup; standardized module names, includes and lifecycle logging; safer file append behavior; broader build support.

* **API Changes**
  * Driver lifecycle now uses explicit add/remove semantics; C and HAL device type/lookup APIs clarified.

* **Chores**
  * Added module README and Apache‑2.0 license; updated build configuration to include the new module.

* **Fixes**
  * Updated tests and object file handling to behave correctly.
