Update README

Analyze a project's codebase and update its README.md to accurately reflect the current state.

Instructions

1. Read the current README.md to understand existing structure
2. Read package files (pubspec.yaml, package.json, Cargo.toml, pyproject.toml, go.mod, etc.) for metadata
3. Use Glob to understand directory layout (**/*.{js,ts,py,go,rs})
4. Compare README against actual codebase for discrepancies
5. Update only sections that are outdated or incorrect
6. Provide a summary of changes made

What to verify

• Dependencies: Match actual package files
• Features: Reflect capabilities found in code
• Installation: Steps work with current setup
• Usage examples: Code snippets are accurate
• File references: Mentioned paths exist
• Configuration: Options are complete

Rules

• MUST preserve existing README structure when possible
• MUST keep any badges, images, or custom formatting
• MUST use relative links for internal documentation
• Never add sections that weren't requested
• Never remove sections without explicit approval
• Never fabricate features not found in the codebase

Output

After updating, summarize:

• Sections updated
• What was added or removed
• Anything needing manual review
