fix(sentry): keep a live-heartbeat native capacity retry out of Sentry (#19320)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The server sends unexpected run failures to Sentry, and it keeps
known, recovered failures local
> - A native Codex "model at capacity" failure gets an automatic retry.
That failure must stay out of Sentry while its retry owns recovery
(#18295, #19051)
> - The check reads the `nativeProviderFailure` diagnostic from the
failed run's `resultJson`. On the live heartbeat path, the failed-status
write replaces `resultJson` with the adapter's copy, and that copy has
no diagnostic
> - So every live-path capacity failure with a scheduled retry still
goes to Sentry. Only the reconciliation path, which the tests cover,
kept the failure local
> - This pull request removes the diagnostic check. The scheduled retry
run is the proof
> - The benefit is that recovered capacity failures no longer create
Sentry noise on the normal live path

**What happened?**
A native Codex run failed with `native_provider_overloaded`. The
committed status decision scheduled the automatic capacity retry, and
the retry run existed before the report. The run failure still went to
Sentry. In a staging sample, every live-path capacity failure since
#19051 was reported (1 of 1).

**Expected behavior**
When the `native_provider_overloaded` retry run exists for the same
task, the failed run does not go to Sentry. The retry reports its own
outcome.

**Steps to reproduce**
1. Run a native Codex agent through the live heartbeat path
(`finalizeNativeRun` without `projectRunStatus`).
2. Let the provider return `serverOverloaded`. The status decision
schedules the capacity retry.
3. The heartbeat writes the terminal `failed` status with the adapter's
`resultJson`, and `emitTerminalAgentTaskRun` calls `reportRunFailure`
with that row.
4. The row has no `nativeProviderFailure`, so
`isScheduledNativeCapacityRetry` returns false and the event goes to
Sentry.

**Relevant logs or output**
The failed run row later shows `nativeProviderFailure:
codex/server_overloaded`, because a later reconciliation write restores
it. The row that the heartbeat write reports does not have the field.
The same overwrite also explains the missing `finalizationReasonCode`
that #19051 fixed.

## What Changed

- `server/src/services/run-failure-report.ts`:
`isScheduledNativeCapacityRetry` no longer requires
`resultJson.nativeProviderFailure`. The run must still be native and
failed, carry `native_provider_overloaded`, have a native task, have no
signal, and not be in setup. The same-task successor with
`scheduledRetryReason: native_provider_overloaded` is still required.
- The successor is enough proof. Only the committed capacity status
decision creates that successor, and only `forTerminal` in
`native-provider-failure.ts` produces `native_provider_overloaded`
together with the typed `codex`/`server_overloaded` diagnostic.
- `run-failure-report.test.ts`: a new case keeps the failure local when
the row has only the adapter's `resultJson` (no diagnostic, no
finalization fields) and the successor exists. The "diagnostic is
missing" case now reports only when no retry run exists. The case for a
non-capacity diagnostic with a capacity successor is removed, because
that state cannot occur.
- `doc/observability.md`: the native capacity paragraph now says that
the successor is the proof and that the run's own `resultJson` is not
required.

## Verification

- `pnpm --filter @paperclipai/server exec vitest run
src/services/__tests__/run-failure-report.test.ts`: 284/284 pass with
this change.
- With the `master` version of `run-failure-report.ts`, the new case
fails: 1 failed, 283 passed. So the test catches the bug.
- `native-provider-failure.test.ts`: 57/57 pass.
- `native-provider-overload.integration.test.ts` did not load in my
sandbox, because `@paperclipai/plugin-sdk` was not built. CI must run
it.

## Risks

- Low risk. The change only removes one condition from a Sentry filter.
- These failures still report: no retry run, exhausted or held retries,
other retry lanes, a successor for a different task, legacy runs,
signals, timeouts, setup failures, and unreadable retry evidence.
- The change does not affect run status, retries, recovery, or the `all`
reporting mode.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), agentic coding with tool use
(shell, repository reads, test runs).
