* **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.
