ci: run release Runner protocol and Rust checks in parallel (#13326)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip Cloud deploys verified images from merged source commits.
> - Cloud readiness waits for every release verification check.
> - Runner verification currently runs long TypeScript tests before Rust
checks.
> - These checks can run on independent runners with their own build
directories.
> - This PR runs them in parallel while preserving all checks and the
shared dependency cache.

## Linked Issues or Issue Description

Refs #13194. Related prior work: #13142 and #13259. A search found no
duplicate parallel release-check change.

**What existing behavior does this improve?**

Time from merge to Cloud source verification and deployment readiness.

**Current behavior**

Recent successful runs take roughly 13 minutes from merge to deployable.
In run 34705914878, Runner verification took 11m23s. Protocol tests
finished before Rust tests and API authority checks started.

**Proposed behavior**

Run protocol and Rust verification in two matrix jobs. Cloud readiness
still requires both jobs to pass.

**Reason and benefit**

Remove the serial dependency between independent checks. Expected
improvement is about 2–3 minutes on a typical cached run, until the
image build or server tests become the longest job. This is an estimate;
post-merge timing will confirm it.

**Breaking changes**

Individual release Runner job names gain a lane suffix. Cloud source and
readiness marker names stay the same. PR runner routing is unchanged.

## What Changed

- Split release Runner checks into protocol and Rust lanes. Keep every
constituent of `check:all` exactly once.
- Restore the existing Rust dependency cache in both lanes. Allow only
the Rust lane to save it after warming both build profiles.
- Add coverage and cache authorization regressions. Document the
parallel verification and single cache writer.

## Verification

- Passed 477 workflow and source-verification tests with `node --test
.github/scripts/tests/*.test.mjs
scripts/cloud-source-verification.test.mjs
scripts/__tests__/release-verify-workflow.test.mjs`.
- Passed `actionlint`, `git diff --check`, and the private AWS routing
regression suite.
- Passed local `pnpm -r typecheck` and the standalone `check:runner &&
check:api-authority` lane, including all 1,671 API tests before the
protocol lane had built TypeScript output.
- The broad local protocol run under Node 25 had four failures. The two
affected files passed under CI's Node 24.19.0: 67 passed, 6 platform
skips.
- Local `pnpm test:run` aborted when disk space ran out; local `pnpm
build` could not run afterward. These are local verification limits.
[Linux CI run
34710421424](https://github.com/paperclipai/paperclip/actions/runs/34710421424)
passed full typecheck, all grouped tests, native verification, build,
release dry run, and browser checks. Native protocol CI passed 1,986
tests, plus 1,671 API tests and the Rust suites.
- Latest-head Greptile is 5/5 with no open findings. All 33 current-head
checks are successful or intentionally skipped.

## Risks

- Uses one additional short-lived verification runner per release
verification. The existing AWS exact-master restriction remains in
place.
- The Rust lane warms debug dependencies so its cache save also serves
protocol tests. Both lanes always rebuild workspace code.
- A workflow regression could omit a check. The new coverage test
compares the matrix checks directly with `check:all`; Cloud readiness
depends on the complete reusable workflow.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools, and code
execution. The exact serving model ID and context window are not exposed
by this environment.

## Runner verification dependency cache
`release-verify.yml` caches Cargo dependencies for its `Verify Paperclip Runner`
job using a pinned Rust Cache action. It selects the compiler from the Runner
package's `rust-toolchain.toml` before computing the cache key. Compiler and Cargo
metadata changes select a new cache; the `release-runner-v1` shared key lets
callers of this reusable verification workflow reuse the same dependency cache.
`release-verify.yml` runs `Verify Paperclip Runner` on two independent runners.
The protocol lane runs `check:eval-kernel` and `check:protocol`. The Rust lane
runs `check:runner` and `check:api-authority`. Together they retain every check
in `check:all`; both lanes must pass before Cloud source verification or
readiness can succeed. A failed lane does not cancel the other lane.
Workspace crates and installed Cargo binaries are excluded. Every run still
builds the Runner workspace and runs `check:all`, including the Rust and
TypeScript tests. Only an own-repository master-push run verifying that push's exact
SHA can restore the cache, and only a successful run saves it. PR, tag, and
manual candidate verification compile without this cache. A miss or eviction costs compilation time but does not change the checks.
To discard old dependency caches, increment the shared-key version and let the
next successful master verification warm it again.
Both lanes restore Cargo dependencies with the pinned Rust Cache action. The
compiler comes from the Runner package's `rust-toolchain.toml` before the action
computes its key. Compiler and Cargo metadata changes select a new cache. The
existing `release-runner-v1` shared key avoids separate copies for these lanes.
Only the Rust lane saves this cache. After verification it also runs `build:rust`
to warm the debug dependencies used by the protocol lane; its own tests already
warm release dependencies. The cache writer is shorter than the protocol lane.
Workspace crates and installed Cargo binaries are excluded. Every run rebuilds
workspace code and runs all assigned checks, including on a cache hit. Only an
own-repository master-push run verifying that push's exact SHA can restore the
cache, and only a successful Rust lane saves it. PR, tag, and manual candidate
verification compile without this cache. A miss or eviction costs compilation
time but does not change the checks. To discard old dependency caches, increment
the shared-key version and let the next successful master verification warm it.
The trust boundary is the protected master branch, not the cache-key text.
GitHub does not let master restore caches created by a child branch, sibling
