CLI-152 Regenerate README docs

No description provided.

[sonar-review-alpha]

Summary

This PR regenerates the README documentation to reflect changes in the CLI:

• Command rename: sonar analyze a3s → sonar analyze sqaa (reflects product branding update)
• Enhanced documentation: Options table added for sonar analyze sqaa with --file, --branch, and --project parameters
• New command: sonar verify added with description "Analyze a file for issues"

The large diff reflects a documentation regeneration process (likely auto-generated from CLI help text or a documentation script). Focus review on the README.md changes to verify the command names, descriptions, and option documentation are correct.

What reviewers should know

This PR comment provides reviewers with:

1. High-level overview of what changed in the documentation
2. Key details about the command rename (A3S → SQAA)
3. Information about newly documented options and commands
4. Guidance on where to focus review effort (README.md changes)
5. Context that this is a documentation regeneration, not feature development
