Greptile Summary

This PR adds a complete Greptile integration to enable AI-powered codebase search and Q&A capabilities within Sim workflows. The implementation includes four tools (query, search, index repository, and status checking), a unified block interface, comprehensive documentation, and minor copilot panel styling improvements.

Key Changes:

• Implemented four Greptile API tools with proper credential handling using user-only visibility
• Created a unified block with conditional UI that switches between operations
• Added TypeScript types and utilities for repository parsing
• Documented all tools with input/output specifications
• Disabled the search tool in the block UI due to Greptile API v1 deprecation (though the tool implementation remains)
• Improved copilot markdown rendering with better spacing for paragraphs, lists, and headings
• Removed unnecessary inline comments from markdown renderer

Technical Highlights:

• Proper URL encoding for repository IDs in status endpoint
• Clean separation of concerns with dedicated files for each tool
• Repository string parsing supports both short format (owner/repo) and full format (github:main:owner/repo)
• API key and GitHub token correctly use user-only visibility per project guidelines

Confidence Score: 5/5

• This PR is safe to merge with no critical issues found
• The implementation is clean, well-structured, and follows project conventions. Credentials are properly configured with user-only visibility as required. All tools have comprehensive type definitions, the code is modular and maintainable, and documentation is thorough. The styling changes are minor and non-breaking.
• No files require special attention
