Migrate test runner from bun:test to vitest

[firecow]

• Migrate from bun:test to vitest for file-level parallelism via worker threads
• Replace bun:test imports with vitest equivalents in 6 test files
• Add vitest.config.ts with globals, 60s timeout, FORCE_COLOR, and v8 coverage
• Update CI workflow depcheck ignores and CLAUDE.md docs
• CI test job: ~6m10s (bun:test) → ~4m23s (vitest), ~30% faster

Summary by cubic

Migrated the test runner from bun:test to Vitest for parallel execution and consistent V8 coverage, cutting test time and centralizing test config.

• Refactors

  • Swapped bun:test APIs for Vitest (vi.spyOn, vi.restoreAllMocks) in 6 files and fixed related type references.
  • Added vitest.config.ts with globals, 60s timeout, FORCE_COLOR, V8 coverage; kept Vitest default excludes and added project exclude for .gitlab-ci-local.
  • Updated tsconfig to include vitest/globals.
  • Switched package.json scripts to vitest run (tests, test-except-dind, coverage).
  • Added Vitest and @vitest/coverage-v8 to devDependencies; updated CI depcheck ignores and testing docs; regenerated bun.lock.

• Migration

  • Run all tests: bun run test. Targeted runs: bunx vitest run tests/.
  • Coverage: bun run coverage outputs text and lcov to ./coverage.
  • Avoid full local runs; use targeted tests as documented.
