feat: add dirty repository check with --allow-dirty flag (#243)

This pull request includes changes to ensure that Kwaak does not start
the TUI or run the agent if the current directory contains uncommitted
changes ("dirty" state), unless overridden with the `--allow-dirty`
flag.

- Added `--allow-dirty` flag for command-line parsing in `src/cli.rs`.
- Implemented logic in `src/main.rs` to check for a dirty git directory
and prevent command execution unless `--allow-dirty` is specified.
- Adjusted test cases in `tests/cli_init.rs` to commit changes or
incorporate the `--allow-dirty` flag where appropriate.
- All existing and new tests are passing.

Fixes #167
