fix: harden release registry verification against npm lag (#4816)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Its release automation publishes canary packages to npm and then
validates the published registry state before considering the release
healthy
> - The failing canary run `25139465018` showed that npm can expose a
newly published version through version-specific endpoints before the
root package document has fully converged
> - That made a successful canary publish look like a failed release
because the verifier trusted stale root metadata too early
> - This pull request hardens the registry verification path by
preferring version-specific manifest checks, retrying
convergence-sensitive failures, and distinguishing permanent failures
from propagation lag
> - While validating that change in CI, a separate teardown race in
`heartbeat-stale-queue-invalidation.test.ts` surfaced and was hardened
so the PR could pass reliably
> - The benefit is that transient npm propagation lag no longer fails a
successful canary publish, while genuine registry-state and
dependency-integrity failures still stop the release flow promptly

## What Changed

- Hardened `scripts/verify-release-registry-state.mjs` so it prefers
version-specific manifest resolution over stale root metadata, adds
bounded registry-fetch timeouts, and classifies failures as retriable vs
non-retriable.
- Updated `scripts/release-lib.sh` and `scripts/release.sh` so
post-publish registry verification retries only convergence-sensitive
failures and reports immediate permanent failures clearly.
- Expanded `scripts/verify-release-registry-state.test.mjs` with
regression coverage for stale root metadata, fetch timeout behavior,
peer dependency range handling, non-retriable canary-latest cases, and
related verifier edge cases.
- Hardened
`server/src/__tests__/heartbeat-stale-queue-invalidation.test.ts`
teardown to tolerate the late-comment foreign-key race that CI exposed
while validating this branch.

## Verification

- `pnpm run test:release-registry`
- `node --check scripts/verify-release-registry-state.mjs`
- `bash -n scripts/release.sh && bash -n scripts/release-lib.sh`
- PR checks passed on head `5c422600fc12acac61f6b7c267a4dc915df622b1`:
`policy`, `verify`, `e2e`, `security/snyk`, and `Greptile Review`

## Risks

- Low risk. The main behavioral changes are limited to release
automation and verifier retry semantics, plus a test-only teardown
hardening for a CI race.

> I checked [`ROADMAP.md`](ROADMAP.md). This is a narrow release bugfix
and does not overlap planned core feature work.

## Model Used

- OpenAI Codex via Paperclip `codex_local` with tool use and local code
execution enabled. This agent session runs on a GPT-5-class coding
model; the exact backend model ID/context window is not exposed by the
local adapter runtime.
