zach-hermesandPaperclip 8db826d18a fix(issues): cycle-aware issue_blockers_resolved after terminal reset (#11979)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents resume blocked work through the `issue_blockers_resolved`
wake when every durable blocker is `done`
> - That wake is level-triggered: one ready state produces one wake,
shared by the issue update route, workspace-finalize backstop, and
periodic liveness backstop
> - The ready-state key hashed only the dependent id and blocker set, so
it ignored a later reset from a terminal status back into `blocked`
> - After that reset, completing the same blockers found the previous
cycle's completed wake and suppressed the new continuation
> - This pull request folds the dependent's `blockedTransitionAt` into
the ready-state key, with compatibility for old no-cycle keys
> - The benefit is that a reset blocked issue receives exactly one new
wake without watchdog status repair or a change to blocker edges

This change does not auto-flip `blocked` to `todo`. The wake is the
continuation. It also does not treat cancelled blockers as resolved.

**What happened?**
A blocked assigned issue that was previously `done` or `cancelled`, then
reset to `blocked` on the same blocker set, did not receive
`issue_blockers_resolved` when those blockers later returned to `done`.
A completed wake from the previous cycle reused the same level-triggered
state key and suppressed the new wake. Route-time emit,
workspace-finalize backstop, and periodic liveness backstop all used
that helper.

**Expected behavior**
When every durable blocker is `done`, a currently `blocked` assigned
issue must receive exactly one valid `issue_blockers_resolved`
continuation for the current blocked cycle. A completed wake from an
earlier cycle must not suppress it. Watchdog `blocked` → `todo` repair
must not be required.

**Steps to reproduce**
1. Assign issue B, block it on issue A, mark A `done`, and let B receive
`issue_blockers_resolved`.
2. Mark B `done`.
3. Reset A to `todo` and reset B from `done` to `blocked` on the same A
id. This refreshes `blockedTransitionAt`.
4. Mark A `done` again.
5. Observe that B stays `blocked` with no new `issue_blockers_resolved`
wake.

## What Changed

- Extend `buildIssueBlockersResolvedWakeStateKey` so the digest includes
the dependent's `blockedTransitionAt` as UTC ISO-8601, or `none`
- Thread `blockedTransitionAt` through `listWakeableBlockedDependents`,
both route emit sites, and both backstop candidate selects
- Keep compatibility: new cycle-aware keys suppress in idempotent
statuses; old no-cycle state keys suppress when in-flight, or when
completed and `requestedAt >= blockedTransitionAt` (or the cycle is
null); legacy per-edge keys stay in-flight-only
- Do not rewrite `blockedByIssueIds`, auto-flip `blocked` → `todo`, or
delete historical wake rows
- Add helper, route, restore, chained dependent, and backstop tests for
the reset cycle

## Verification

```
pnpm --filter @paperclipai/server exec vitest run \
  src/__tests__/issue-dependency-wakeups-routes.test.ts \
  src/__tests__/heartbeat-issue-liveness-escalation.test.ts \
  src/services/issue-dependency-wakeups.ts \
  src/services/issue-dependency-wakeups.test.ts
```

Local result: all named tests passed (helper 9, routes 8, liveness 26).

## Risks

- Deploy overlap: in-flight and same-cycle completed wakes still exist
under the old no-cycle key. The lookup keeps those as suppressors so
this change does not enqueue a duplicate in the current cycle.
- A completed old-key wake from before the current `blockedTransitionAt`
no longer suppresses. That is the intended fix.
- No schema migration. Rollback is revert of this PR.
- This does not change cancelled-blocker semantics or watchdog `blocked`
→ `todo` repair.
