Standardize on top-level triggerer property (#361)

* Standardize on top-level `triggerer` property

- Rename `triggeringUser` → `triggerer` as the single top-level payload property
- Remove redundant `triggerer` from `FixReviewEvent`, add `approvedOnly` boolean
- Auto-apply `approved_by` filtering in `get_review_comments` when `approvedOnly` is set
- Auto-assign created PRs to the triggerer
- Simplify `AddressReviews` mode prompt
- Accept both `triggerer` and `triggeringUser` in schema for backward compat

* Address review feedback: simplify approved_only, remove addAssignees, drop approved_by param

* Fix formatting in `action/mcp/pr.ts`

* re-add triggeringUser backward-compat fallback in payload schema

* auto-assign created PRs to the triggerer

* Revert "auto-assign created PRs to the triggerer"

This reverts commit c088c425fea33793eb299a001ffd253798d2c674.

* Revert "re-add triggeringUser backward-compat fallback in payload schema"

This reverts commit ae5b3cb3f1377cd4a634b2d48962c785c31013f3.

* backend compat

* tweak prompt to ensure compat

* Address review feedback

* chore: remove triggeringUser fallback
