📝 Improve package description and keywords

Update Cargo.toml with more descriptive package metadata

Enhance the project description to better communicate Git-Iris's
full feature set, highlighting code reviews, changelogs, and release
notes capabilities alongside commit assistance.

Optimize keywords list to fit within crates.io's 5-keyword limit
while maintaining discoverability with focused terms: git, ai, cli,
devtools, and productivity.
