Summary

Updates the Supabase skill so agents do not assume the MCP SQL execution
tool is exposed exactly as execute_sql.

The updated guidance:

• discovers SQL tools by capability, description, and input schema
• accepts namespaced or transformed tool names
• invokes the exact tool name returned by the current registry
• only falls back to MCP connection troubleshooting when no compatible
  SQL execution tool can be discovered
• updates other execute_sql references to avoid requiring the exact name

Fixes #189

Testing

• pnpm test

Hi maintainers,
The Skills CI workflow appears to have expired after waiting for approval for 30 days. No CI jobs were executed.
Could someone please review the PR and approve a fresh workflow run? I'm happy to address any feedback or make additional changes if needed.

Thanks!
