feat: add category management(add, edit, remove) (#44)

* feat: add category subcommands (list/add/edit/remove)

- Refactor sym category to parent command with subcommands
- Add sym category list (moved from sym category)
- Add sym category add <name> <description>
- Add sym category edit <name> --name/--description
- Add sym category remove <name> (blocked if rules reference it)

* feat: add MCP tools for category management

- add_category: add new category with name and description
- edit_category: edit category name/description, updates rule refs
- remove_category: remove category (blocked if rules reference it)

* test: add MCP category management tests

- TestAddCategory: success, duplicate, empty name/description
- TestEditCategory: description update, rename with rule refs, conflicts
- TestRemoveCategory: unused category, rules blocking, not found

* feat: add dashboard API endpoints for category management

- GET /api/categories: list all categories
- POST /api/categories: add new category
- PUT /api/categories/{name}: edit category
- DELETE /api/categories/{name}: remove category (blocked if used)

* feat: add category management UI to dashboard

* fix: move category UI to Global Settings and fix input sizing

* fix: preserve categories when applying template

* feat: auto-add missing categories when applying template

* feat: include category description in LLM routing prompt

* fix: correct jsonschema tag format for MCP category tools

* feat: add batch operations for category management

- MCP tools: batch-only mode (categories[], edits[], names[])
- CLI commands: single + batch mode with --file flag
- Partial failure handling with success/fail reporting

* feat: simplify template category handling

- Add category array to template files (node, python, go)
- Overwrite categories when applying template (remove merge logic)
- Fix LLM provider message in convert dialog

* refactor: improve directory change handling in tests and clean up unused code
