1477d1ecea test: remove the no-op sequential describe modifier (#15286)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Paperclip runs the server and runner test suites with Vitest.
> - Vitest 5 removes the deprecated `describe.sequential` property, so
the pending Vitest 5 upgrade fails the type-check and test jobs.
> - `describe.sequential` only changes behaviour inside a
`describe.concurrent` suite, or when `sequence.concurrent` is on.
> - This repository has neither, so the modifier changed nothing at run
time.
> - The benefit is that the Vitest 5 upgrade can land, and the test
files lose a modifier that did no work.

## Linked Issues or Issue Description

Refs: #12969

## What Changed

- Replace every `describe.sequential` use with a plain `describe` call.
- Drop the `{ concurrent: false }` suite option from the two runner test
files.
- Add a comment to `server/vitest.config.ts` that records why these
suites must run one test at a time.
- Leave the package manifests and the lockfile unchanged.

## Why the modifier did nothing

The Vitest documentation states that `describe.sequential` is useful to
run tests in sequence inside a `describe.concurrent` suite, or with the
`--sequence.concurrent` option. `sequence.concurrent` defaults to
`false`.

This repository satisfies neither condition:

- No test file uses `describe.concurrent`, `it.concurrent`, or
`test.concurrent`.
- `server/vitest.config.ts` sets `sequence.concurrent: false`, with
`maxWorkers: 1`, `maxConcurrency: 1`, and `isolate: true`.
- `packages/paperclip-runner/vitest.config.ts` sets no `sequence` block,
so the `false` default applies.

`packages/db` and `cli` already run the same embedded-Postgres suites
with a plain `describe`, and those jobs are green. The server package
was the only outlier.

The modifier did carry one real piece of knowledge: these suites need
their tests to run one at a time. The new comment in
`server/vitest.config.ts` records that reason next to the setting that
enforces it.

## Verification

- `git grep` for `describe.sequential` returns nothing outside
`node_modules`.
- The author ran the changed server test files under the installed
Vitest 4, and the results match the results without this change.
- Two very large embedded-Postgres test files exceeded the author's
local memory limit, so the CI test jobs cover those two.
- The two changed runner test files have pre-existing local failures
caused by a missing Rust toolchain and a missing global `pnpm` binary.
The failures are identical with and without this change.
- The author type-checked the changed files and found no new error.
- CI must pass the typecheck, build, server test, and runner verify
jobs.

## Risks

- Low risk. Suite execution stays serial, because the Vitest config
enforces it.
- The change adds no dependency and changes no package manifest or
lockfile.
- A future change that turns `sequence.concurrent` on would break these
suites. The new config comment warns against it.

## Model Used

- Claude Sonnet 5 — code edits and local verification.
- OpenAI Codex, GPT-5 — the earlier revision of this branch.

## Test plan

- [x] Every CI check reaches a terminal green state. A pending or queued
check is not a pass.
- [x] The `Typecheck + Release Registry` job passes. This change must
not introduce a type error.
- [x] The `Build` job passes.
- [x] The server test jobs and the runner verify jobs pass.
- [x] Greptile re-reviews this commit set and posts a passing verdict.
The dependabot waiver does not apply to this pull request.
- [x] `mergeable` reads `MERGEABLE` as a terminal value.
