chore: update dependencies

[JoviDeCroock]

Summary

Updates the dev toolchain and the plugin's bundled dependencies, keeping everything green (52/52 e2e + unit tests pass, verified from a clean --frozen-lockfile install).

Tooling majors

• vitest 0.34 → 4.1 — the removed --single-thread flag is replaced by --no-file-parallelism; vite 8 is pinned as a root devDependency so vitest's vite@^6||^7||^8 peer resolves (the lockfile otherwise kept a stale vite 5)
• prettier 2 → 3 — prettier.format is async now, so the d.ts renderChunk hook in the rollup config awaits it
• husky 8 → 9 — prepare script is now husky, hook file header removed (was deprecated), stale husky 4 config block dropped from package.json
• rollup plugins: babel 7, commonjs 29, node-resolve 16, terser 1, typescript 12
• lint-staged 17, dotenv 17, @actions/core 3, @actions/github 9, @changesets/get-github-info 0.8, @types/node 22 (matches CI's Node 22)

Bundled (published) deps

• graphql-language-service 5.2 → 5.5 — completion entries gain label, detail, type, documentation, and deprecation metadata (snapshots updated accordingly)
• lru-cache 10 → 11 — requires Node 20+
• @sindresorhus/fnv1a 2 → 3 — returns BigInt, so the diagnostics cache key type changed
• In-range: typescript 5.3.3 → 5.9.3, rollup 4.62, @gql.tada/internal 1.2.1, changesets 2.31, gql.tada 1.11.2

A changeset (patch) is included for the bundled dependency changes.

Test fixes required by the updates

• TypeScript 5.9's tsserver no longer emits the setTypings event; the graphqlsp and misconfiguration e2e suites waited for it in beforeAll and timed out. They now wait for projectLoadingFinish, and the graphqlsp suite additionally polls completionInfo until the async schema load completes (mirroring the existing waitForDiagnostics pattern).
• Snapshots updated for the new completion metadata fields and vitest 4's inline-snapshot quote escaping.
• test/e2e/fixture-project-tada/introspection.d.ts was regenerated by the plugin during the test run with @gql.tada/internal 1.2.1.

Deliberately held back

• graphql stays on 16.x — 17.0 is a freshly released major on the plugin's peer surface; fixtures pin ^16
• TypeScript stays on 5.x — 6.0 affects the tsserver internals the plugin builds against
• Babel plugins stay on 7.x — the 8.x plugins require @babel/core 8
• Test fixture dependencies (urql, @types/react) stay pinned to avoid meaningless snapshot churn

These are better done as separate, focused PRs.

Verification

rm -rf node_modules && pnpm install --frozen-lockfile
pnpm --filter @0no-co/graphqlsp run build   # ok
pnpm run test:e2e                           # 11 files, 52/52 passed
pnpm peers check                            # no issues
