refactor(deps-dev): bump vitest from 3.2.4 to 4.1.8 (#7581)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Test infrastructure across server, ui, packages/* runs on Vitest
> - Dependabot opened a narrow bump (3.2.4 → 3.2.6), but the wider
workspace is on 3.2.4 and the major-version bridge to v4 needs a
coordinated change set across configs and tests
> - Staying on 3.x indefinitely leaves us behind on Vitest 4 (perf,
pool, and config improvements) and forces repeated patch-only dependabot
churn
> - This pull request upgrades Vitest to 4.1.8 across the workspace,
updates `server/vitest.config.ts` and `scripts/run-vitest-stable.mjs`
for the new API, and adjusts two UI tests for the new assertion
semantics
> - The benefit is a single, coherent Vitest 4 upgrade that supersedes
#7570 and gets us on the supported major line

## What Changed

- Bump `vitest` from `3.2.4` to `4.1.8` across root, `server`, `ui`, and
all `packages/*` (including plugin examples and sandbox providers)
- Update `server/vitest.config.ts` for Vitest 4 config surface
- Update `scripts/run-vitest-stable.mjs` to match the new runner
behavior
- Adjust `ui/src/components/CommentThread.test.tsx` and
`ui/src/components/MarkdownEditor.test.tsx` for Vitest 4 matcher/timing
semantics
- Refresh `pnpm-lock.yaml`

## Verification

- `pnpm install` resolves cleanly with the new lockfile
- `pnpm -w -r test` (server, ui, packages) runs under Vitest 4.1.8

## Risks

- Major-version Vitest bump: behavioral changes in pools, fake timers,
and matcher strictness can surface flake. Test config and the two UI
tests were updated to match v4 semantics; broader test runs should be
watched on CI before merge.
- Supersedes dependabot PR #7570 (3.2.4 → 3.2.6); that PR should be
closed.

## Model Used

- Claude (Anthropic) — `claude-opus-4-7`, extended thinking, tool use
enabled
