docs(command-palette): rewrite guide to match actual implementation

- Updated to reflect 13 tests (6 unit + 7 live_gui) instead of hypothetical async test
- Removed Everything mode and async context preview sections (not yet implemented; marked as future work)
- Updated Commands Registry section to reference actual src/commands.py file
- Added Implementation section with file layout and Command/CommandRegistry/CommandModal reference
- Added Built-in Commands table reflecting the actual 11 commands shipped
- Added Adding Custom Commands section with decorator and explicit-Command patterns
- Added Keyboard Reference table
- Updated Testing section with accurate coverage and test pattern
- Moved unimplemented features (Everything mode, user-defined commands, plugin system) to Future Work
