Fix: resolve_pr_parallel uses non-existent scripts

[ajrobertsonio]

Summary

• Replace references to bin/get-pr-comments and bin/resolve-pr-thread with standard gh CLI commands
• These scripts were never created and don't exist in the plugin or user projects
• Commands now work in any repository without custom scripts

Test plan

• Run /resolve_pr_parallel on a PR and verify it fetches comments without errors
• Verify the command uses gh api and gh pr view instead of missing scripts

Fixes #147

Thanks for catching this! You were right that those bin/ scripts were missing from the plugin.

I've fixed this by converting resolve_pr_parallel from a command to a proper skill with the scripts bundled:

• skills/resolve-pr-parallel/scripts/get-pr-comments — GraphQL query for unresolved threads (now auto-detects owner/repo instead of hardcoding)
• skills/resolve-pr-parallel/scripts/resolve-pr-thread — GraphQL mutation to resolve threads

This keeps the GraphQL power (filtering unresolved/non-outdated threads, programmatic resolve) while making it portable across repos.

Closing this since the fix is included directly — thanks again for flagging it! 🙏
