feat(review): add findings fix workflow

[peyton-alt]

https://entire.io/gh/entireio/cli/trails/322

Summary

• add local review manifests so one review session id resolves sibling agent outputs and aggregate summaries
• add entire review --findings and entire review --fix [session-id] / --all workflows
• add source/finding selectors plus saved review_fix_agent preference for aggregate or multi-agent fixes
• print follow-up fix commands after review completion

Verification

• go test ./cmd/entire/cli/review ./cmd/entire/cli ./cmd/entire/cli/settings -count=1
• mise run lint
• mise run test
• mise run build
• local smoke with PATH override: entire review --findings

---

Note

Medium Risk
Adds new entire review sub-modes that persist local manifests under the git directory and can spawn a follow-up agent session to apply findings, so regressions could impact review UX/CLI behavior and local state handling.

Overview
Adds a local review findings workflow to entire review: new --findings mode to browse stored outputs and new --fix [session-id] (optionally --all) mode to select sources/findings and launch a normal agent session with a targeted “fix these findings” prompt.

Persists each completed review run as a local manifest (per-agent outputs plus optional multi-agent synthesized aggregate) and prints follow-up entire review --fix ... commands after review completion; multi-agent synthesis now exposes its final result via an OnResult callback so it can be captured into the manifest.

Extends settings with a review_fix_agent preference (picked/saved during --edit and used for aggregate/multi-agent fixes) and ensures fix runs strip ENTIRE_REVIEW_* env vars before launching the fix agent.

Pull request overview

This PR adds a local “review findings” + “apply fixes” workflow to the entire review command by persisting per-run manifests (including sibling agent outputs and optional aggregate synthesis) and introducing new CLI entry points for browsing and applying findings, with a saved default fix-agent preference.

Changes:

• Persist local review manifests per entire review run (agent session IDs, outputs, and optional aggregate synthesis result) and print follow-up --fix commands after completion.
• Add entire review --findings for browsing manifests and entire review --fix [session-id] [--all] for selecting sources/findings and launching a fix agent.
• Add review_fix_agent setting and picker/selection logic to remember the preferred agent for aggregate/multi-agent fixes.
