Fix wt run command worktree error (#7)

The wt run command now properly handles the '^' symbol to reference the
default worktree, consistent with how wt switch handles it.

Changes:
- Added special handling for '^' in run command (cli.py)
- Added three new tests for run command functionality
- Updated notes.md with implementation details

Fixes issue where 'wt run ^ "git status"' would error with "Worktree '^'
not found" instead of running in the default worktree.

All 61 tests passing.

+7. **Missing Special Symbol Support in `wt run`**
+   - Problem: The `wt run` command didn't support the `^` symbol for the default worktree, while `wt switch ^` did
+   - Error: Running `wt run ^ "git status"` resulted in "Error: Worktree '^' not found"
+   - Solution: Added special handling for the `^` symbol in the `run` command (cli.py:373-380) to resolve it to the default worktree name before looking up the worktree
+   - Implementation: Added check `if name == "^":` to get the default worktree using `ctx.manager.get_default_worktree()` and then use its name
+   - Tests: Added three new tests in test_cli.py:
+     - `test_run_command`: Tests running a command in a normal worktree
+     - `test_run_command_with_default_symbol`: Tests running a command using `^` symbol
+     - `test_run_command_nonexistent_worktree`: Tests error handling for non-existent worktrees
+   - Lesson: Always ensure consistency across commands - if a special symbol works in one command, users will expect it to work in related commands too
+
 ### Future Improvements
 
 1. **Increase CLI Test Coverage**: Add more edge case tests for CLI commands
