Add memo git information to commit messages #118

Summary

• Add memo-specific git information to commit messages
• Include memo version or identifier in commit metadata
• Update system prompt to include this requirement

Description

Currently memo creates commits without any memo-specific identification. We should:

1. Add memo version or identifier to commit messages
2. Include memo git information in commit metadata
3. Update system prompt to ensure this happens consistently

Implementation Options

1. Commit Message Footer: Add 🤖 Generated with Memo Code vX.X.X footer
2. Commit Message Prefix: Use [memo] prefix in commit messages
3. Git Config: Set commit author/committer information for memo-generated commits
4. Trailer Lines: Add Signed-off-by: memo <memo@example.com> or similar

Proposed Solution

Add a standardized footer to all memo-generated commits:

🤖 Generated with Memo Code vX.X.X

Technical Requirements

• Extract memo version from package.json or version file
• Update commit message template in system prompt
• Ensure consistent formatting across all commit types
• Add configuration option to disable if needed

Acceptance Criteria

• All memo-generated commits include memo identifier
• Version information is accurate and up-to-date
• System prompt updated with commit message guidelines
• Documentation for commit message format
• Optional configuration to disable memo identifier
