reorder prompt sections: task-first with dynamic TOC (#513)

* reorder prompt sections: task-first with dynamic TOC

put the actual task at the top of the prompt for primacy, add a
dynamic table of contents, and push system/runtime metadata to the end.

new section order: TOC → YOUR TASK → PROCEDURE → EVENT CONTEXT →
SYSTEM → LEARNINGS → RUNTIME

Made-with: Cursor

* enforce clean working tree: continue session if agent leaves uncommitted changes

after each agent run, check `git status --porcelain`. if dirty, resume
the same session with instructions to commit on a new branch, push, and
open a PR. retries up to 3 times before giving up.

- claude code: capture session_id from result event, use --resume <id>
- opencode: use --continue to resume the last session
- remove --no-session-persistence from claude (needed for --resume)
- update Task mode to clarify branch/push/PR is the default finalize step

Made-with: Cursor

* log full prompt in collapsible group for debugging

Made-with: Cursor

* fix: format tool refs in buildCommitPrompt via formatMcpToolRef

* enforce clean git status: general instructions, stop hook, and Task mode

Made-with: Cursor

* fix: rename stale titleBody references after body leak fix
