feat(cli): enhance install and removal UX with progress visibility and theming

- Introduced visible progress stages during installation, including source resolution and artifact selection.
- Improved separation between live transcript output and final summaries, ensuring clarity.
- Removed redundant recap text from installation summaries.
- Centralized terminal styling using a configurable theme system, allowing for warm defaults and user overrides.
- Added support for hex colors and named colors in the configuration.
- Updated tests to verify new behaviors and configurations.
