DottaandClaude c58356003f fix(native): give run finalization its own retry budget (#20555)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs save an accepted result. Then a finalizer applies that
result to the issue.
> - After a control-plane restart, recovery can resume the same run.
Each resume uses one provider attempt (`coordinator.attempt`).
> - The finalizer used the same `coordinator.attempt` value as its own
retry budget. After three resumes, `attempt` was 3. So the first
transient finalization failure made the coordinator `terminal_failure`.
> - The result was then lost: the issue stayed `in_review` and no Retry
was available. This breaks the rule that a restart must not leave a task
stuck.
> - This pull request gives finalization its own retry count. Provider
attempts no longer use up finalization retries.
> - The benefit: a resumed run that finishes its turn also finishes its
task, and finalization stays bounded.

## Linked Issues or Issue Description

**What happened?**
In restart-chaos wave `w-20261110T044338-s20385`, task t03 (local,
Codex, three K1 SIGKILL restarts, `--db-pressure 4`), recovery resumed
run `d5d0e839` three times (`providerAttempt: 3`). The resumed turn
completed and the server logged `run.result.accepted`, and the run ended
`succeeded`. The first finalization hit `NativeStatusRaceError` three
times under row contention. `recordRetryableFailure` then compared
`coordinator.attempt` (3) with its limit of 3 and wrote
`terminal_failure` / `native_finalization_retry_exhausted`. The run's
`execution.nextAction` is "Reassess against the latest authoritative
issue status version.", which only the `status_cas_exhausted` branch
writes. The second finalize call 2 s later got
`native_finalization_terminal_failure` from `claimCoordinator`. The
issue stayed `in_review` with `canRetry=false`.

**Expected behavior**
A transient finalization failure must stay retryable. The finalizer must
apply the saved result without another provider turn. Finalization must
still have a limit.

**Steps to reproduce**
1. Resume a native run until its coordinator `attempt` is 3, for example
with three restarts.
2. Let the resumed run save an accepted result.
3. Make the first finalization fail with a retryable error.
4. Before this fix, the coordinator goes directly to `terminal_failure`.
The new test
`server/src/__tests__/native-finalization-retry-budget.test.ts`
reproduces this order.

**Paperclip version or commit**
The wave ran at e2b0290213. The bug is still on master at 902f376796. I
found no later merged PR that changes this check.

## What Changed

- `native-run-finalizer.ts`: `recordRetryableFailure` counts failed
finalizations of the saved result in
`heartbeat_runs.result_json.finalizationFailureCount`. It ends retries
after 3 failures. It no longer reads `coordinator.attempt`, which counts
provider attempts. The count goes on the run because each claim clears
the coordinator's `failure_detail`. Workspace-scope failures keep their
existing `workspaceFinalizeAttempt` budget.
- New regression test `native-finalization-retry-budget.test.ts`: a
coordinator saved at `attempt: 3` with no count stays
`retryable_failure` after the first failure. It goes to
`terminal_failure` only after the third failure.

## Verification

- `cd server && npx vitest run
src/__tests__/native-finalization-retry-budget.test.ts
src/__tests__/native-finalization-recovery.test.ts`: 37 tests pass.
- The new test fails on the unchanged finalizer (`terminal_failure`
received, `retryable_failure` expected). It passes with the fix.
- `pnpm verify` (selected tests).
- I did not run a live chaos replay. The evidence is the wave's run
events, its server log, and the code path.

## Risks

- Low risk. The only behavior change: runs that used provider attempts
now get their full 3 finalization retries.
- Previous-release story: rows that an older server saved have no
`finalizationFailureCount`. Their count starts at 0, so they get at most
3 more finalization tries, with no provider work. A coordinator that an
older server already set to `terminal_failure` stays terminal. This PR
migrates nothing.
- If another writer replaces `result_json` without spreading it, the
count can reset. That allows only a few more cheap retries, 30 s apart.
It cannot cause an unbounded loop unless the overwrite repeats.
- Not addressed here: when finalization really runs out of retries for a
succeeded run, the issue still rests `in_review` with a board recovery
card and no Retry. A safe Retry for that case must re-finalize the saved
result, not start a new provider run. That needs a separate change.
