refactor: unify diff logic in git client

Consolidate `Diff` and `DiffWithColor` into a single, parameterized
`Diff` method to reduce code duplication and simplify the `GitClient`
interface.

- Updated `GitClient` interface to support color and exclusion flags.
- Simplified `Model` diff retrieval by calling the unified `Diff`
method.
- Cleaned up redundant UI code.
