fix: remove sys.path.append to restore uvx environment isolation

Removed sys.path.append('.') from server.py:426 that was breaking uvx
environment isolation. This was causing watchdog dependency conflicts
between local development and uvx environments, preventing file watcher
from starting properly in uvx mode.

The fix maintains clean uvx isolation while preserving all functionality:
- File watcher auto-refresh now works correctly in uvx environment
- No dependency conflicts between local and uvx environments
- All existing functionality preserved

Tested with comprehensive file watcher validation:
- New file creation triggers auto-indexing (6s debounce)
- File modifications update index automatically
- Observer status remains healthy

Bumped version to v1.1.1 for this critical uvx compatibility fix.
