Added diesel_migrations crate (v2.3.0) to enable database migration functionality. Updated Cargo.toml and Cargo.lock to include the new dependency along with its required sub-dependencies (migrations_internals and migrations_macros). Also made minor cleanups in the codebase:
- Removed unused UI code from platform README
- Cleaned up LLM server initialization code
- Added additional build dependencies in documentation
- Removed unused `id` and `app_state` fields from `ChatPanel`; updated constructor to accept but ignore the state, reducing memory footprint.
- Switched database access in `ChatPanel` from a raw `Mutex` lock to a connection pool (`app_state.conn.get()`), improving concurrency and error handling.
- Reordered and cleaned up imports in `status_panel.rs` and formatted struct fields for readability.
- Updated VS Code launch configuration to pass `--noui` argument, enabling headless mode for debugging.
- Bumped several crate versions in `Cargo.lock` (e.g., `bitflags` to 2.10.0, `syn` to 2.0.108, `cookie` to 0.16.2) and added the new `ashpd` dependency, aligning the project with latest library releases.
- Created detailed markdown files for keywords such as HEAR, TALK, and SET_USER.
- Added examples and usage notes for each keyword to enhance user understanding.
- Developed templates for common tasks like enrollment and authentication.
- Structured documentation into chapters covering various aspects of the GeneralBots platform, including gbapp, gbkb, and gbtheme.
- Introduced a glossary for key terms and concepts related to GeneralBots.
- Implemented a user-friendly table of contents for easy navigation.
