chore: do not build bin-specific dependencies in lib

[ThomasRubini]

Description

This PR removes bin-specific dependencies from the library, allowing the library to be built without compiling e.g. clap-rs

How Has This Been Tested?

• cargo tree does not list bin-specific deps, while cargo tree -F cli does

📝 Walkthrough

Walkthrough

The pull request makes the CLI components optional by converting clap to an optional dependency, introducing new optional UI dependencies (ratatui, crossterm, indicatif), and establishing a new cli feature that bundles these together. The binary is configured to require this feature, ensuring proper compilation with the feature flag.

Changes

Cohort / File(s)	Summary
Dependency Management Cargo.toml	Made clap optional; added optional dependencies ratatui, crossterm, indicatif; defined cli feature combining all CLI dependencies; marked binary with required-features = ["cli"].
Documentation README.md	Renamed Installation section to CLI Installation and updated the install command to include -F cli feature flag for the binary.

Poem

🐰 With whiskers twitched and feature flags in place,
The CLI now dances to an optional pace,
No more mandatory clap, just when you need,
Clean dependencies bloom from the feature seed! 🌱
