refactor(coding-agent): restructured plugin system and build logic

- Migrated legacy static bundled-module registry to a dynamic Bun-based in-memory plugin system. - Removed over 4,000 lines of manually maintained registry files to reduce maintenance overhead. - Implemented CJS absolute path rewriting and native-addon load hooks to improve FFI dependency resolution. - Standardized binary build processes by centralizing compilation logic into shared utilities.
