refactor: remove Agent preset system, fix run_command enable bug

- Delete preset-manager.ts and preset-bar.ts
- Clean up all preset references from main.ts, types.d.ts, state.ts
- Remove preset modal HTML and CSS, rename temp-slider/modal-actions classes
- Fix run_command tool not being enabled (missing setToolEnabled call)
