Nicky LeachandPaperclip e0e503e1bc fix(server): make blockers-resolved wake dedup level-triggered (#11732)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip uses issue dependencies to pause work until blockers reach
a ready state.
> - A blocked issue with several blockers can miss its wake when the
final blocker completes.
> - The wake deduplication used a historical per-edge key, so an old
completed wake hid the current ready state.
> - This pull request adds a level-triggered key for the sorted set of
blocker issue ids and uses one helper for all wake paths.
> - The benefit is that the final blocker wake can repair a missed wake,
while repeated reconciliation stays bounded.

## Linked Issues or Issue Description

Refs #8009, #7853, and #6719. These public pull requests cover related
dependency-wake and deduplication behavior. This pull request fixes a
separate multi-blocker state-key gap.

**What happened?**
A blocked issue with multiple blockers received no
`issue_blockers_resolved` wake when the final blocker completed. An
earlier completed per-edge wake suppressed the wake for the current
all-ready state.

**Expected behavior**
The final blocker completion must emit one wake for the current ready
state. A later reconciliation pass must not emit a second wake for the
same state.

**Steps to reproduce**
1. Create a blocked issue with at least two blocker issues.
2. Complete one blocker and record its completed per-edge wake.
3. Complete the final blocker.
4. Run the route-time or reconciliation wake path.
5. Confirm that one level-triggered wake exists for the sorted blocker
set.

**Deployment mode**
Local dev from source.

## What Changed

- Add a SHA-256 level-triggered idempotency key from the sorted blocker
issue ids.
- Share one deduplication helper across route-time, finalize-time, and
periodic wake paths.
- Treat state-key rows with idempotent statuses as duplicates.
- Treat legacy per-edge rows as duplicates only while they remain in
flight.
- Record skipped route-time wakes without suppressing later
finalize-time or periodic wakes.
- Add regression coverage for a completed earlier-blocker wake and a
second reconciliation pass.

## Verification

- Run `npx vitest run
server/src/__tests__/issue-dependency-wakeups-routes.test.ts`.
- Run `npx vitest run
server/src/__tests__/heartbeat-issue-liveness-escalation.test.ts`.
- Run `npx vitest run
server/src/__tests__/heartbeat-dependency-scheduling.test.ts`.
- Run `npx vitest run server/src/__tests__/issue-rewake-throttle.test.ts
server/src/__tests__/recovery-stale-issue-lock-sweep.test.ts`.
- Run `tsc --noEmit` on the touched files.

## Risks

The change alters wake deduplication for dependency reconciliation. The
new key uses the full sorted blocker set, so a change in that set
permits a new wake. The regression tests cover the missed-final-blocker
case and repeated reconciliation.

## Model Used

OpenAI Codex, GPT-5, tool-use model with code execution and repository
review support.
