feat: add reporting tools and misc fix bugs

[aaronsteers]

Introduce tools for reporting progress and issues back to the manager.

Summary of Changes:

1. Added new tools for reporting status updates and issues.
2. Added "handback" handoff from developer to manager - resolves an issue where the manager tries to start over each time, slowing the process down significantly (was taking 10 minutes, now 4-5).
   • Context: Realtime: Handoffs don't hand back up to original agent openai/openai-agents-python#1197 (comment)
3. Readiness report is now always stored adjacent to the manifest.yaml if we have rights to write it. (Fale gracefully otherwise.)
4. Manager gets tools to review the progress logs and review the last-generated readiness report.
5. Fix various bugs and update the Pydantic dependency to the latest version.

@pedroslopez - FYI

Also, added a while back but working better now, CI pushes auto-kickoff a couple connector builds:
