theme: add Warp terminal theme support (#42)

* theme: add Warp terminal theme support

Add support for Warp terminal theming with proper template and integration.
- Add warp.yaml template with standard theme variables
- Implement apply_warp function with correct 'darker'/'lighter' values
- Integrate with main theme application pipeline via enableWarp config

* warp: improve theme generation and use proper data directory

- Use gen_replace with hash=True for consistent color formatting
- Remove # symbols from template to avoid double hashes
- Replace warp_mode manually after gen_replace instead of adding to colors dict
- Use data_dir for XDG-compliant theme location
