Handle unsupported git commands

[Luladjiev]

This pull request introduces a new version of lgit (v0.9.0) with significant improvements focused on usability, documentation, and compatibility. The most important changes include adding a "git command fallback" feature that allows users to run any git command directly through lgit, a major enhancement and expansion of the README.md for better onboarding and contribution, and internal code changes to support external git commands.

Feature additions and compatibility:

• Added "git command fallback" functionality: users can now run any git command through lgit, either implicitly or explicitly using the -- separator. This is supported by a new External command variant in src/cli.rs and the new src/commands/git_fallback.rs implementation. [1] [2] [3] [4] [5] [6]

Documentation and onboarding improvements:

• Major overhaul of README.md: added badges, table of contents, detailed feature descriptions, installation instructions, quick start guides, command usage examples, configuration details, rationale for using lgit, and a comprehensive FAQ & troubleshooting section. [1] [2] [3]
• Expanded contributing guidelines in README.md: includes step-by-step instructions for development workflow, conventional commit usage, project structure overview, and issue reporting guidelines.

Release and versioning:

• Bumped the crate version in Cargo.toml from 0.8.1 to 0.9.0 to reflect the new features and improvements.
