Summary

Adds a Needs review status to the Roadmap board sweep, between In Progress and Review. Today a ready PR that nobody has reviewed sits in In Progress, mixed in with drafts. This makes the review queue its own column.

How a PR moves

Todo -> In Progress -> Needs review -> Review -> Done

PR state	Status
Draft	In Progress
Latest review from someone requests changes, and they haven't been asked again	In Progress
Ready, no review from another person yet	Needs review (was In Progress)
Changes requested, and every such reviewer was asked to review again	Needs review (was Review)
Reviewed by another person (approve, comment review, dismissed), nothing blocking	Review
Merged	Done (built-in workflow, unchanged)

Issues are unchanged in logic: an issue takes the furthest status of its trusted open linked PRs, so an issue whose PR waits on a reviewer is now in Needs review.

Use cases

• Reviewer looking for work: filter the board by Needs review to see every PR waiting on a reviewer.
• Author pushes fixes and re-requests review: the card goes back to Needs review, so the reviewer sees it again.
• Work in progress: open it as a draft PR. It stays In Progress until marked ready.

Failure and edge cases

• Board has no "Needs review" option yet: cards that would move there are left as they are, and the run is reported as degraded on the private health card. Nothing breaks. Add the option before merging to avoid this.
• Re-request only some blocking reviewers: stays In Progress, as before.
• Re-requested reviewer plus a separate approval: Needs review. The re-requested reviewer still has to look.
• Author's own comments, bots, pending reviews: still don't count as a review, so the PR stays in Needs review.
• Non-draft PR that isn't really ready: shows in Needs review. Use draft PRs for unfinished work.
• Hand moves, Auto status = Off, closed, archived and unknown statuses: handled exactly as before. "Needs review" is now a managed status.

Testing

• 51 tests (46 existing, updated where the expected status changed, plus 5 new): draft vs ready, re-request with a separate approval, issue following a Needs review PR, issue taking its furthest PR, Todo -> Needs review.
• Ran the new tests against the old sweep code: 16 fail, so they check the new rule.
• The privacy test now also checks that "Needs review" never reaches the public log.
