test+docs: finish quality scan cleanup

Tests:
- types.test.mts: delete 10 tautological type-definition tests (TS checks
  them at compile time; runtime assertions gave false confidence)
- spinner/logger/github/promise-queue: replace 8 expect(true).toBe(true)
  with not.toThrow() or drop empty operation bodies
- suppress-warnings: assert kMaxEventTargetListeners symbol is defined
  before checking its value (prevents silent pass on Node symbol rename)
- shadow: control npm_config_user_agent env var to make the empty-binPath
  test deterministic; assert exact boolean result
- sea: replace wall-clock cache-speed budgets with cached-value stability
  (cache is observable via repeated-call equality, not ms timing)
- http-request: replace elapsed>=200 / <2000ms assertions with attempt
  count + onRetry call count (wall-clock is CI-flaky); 4 tests updated
- constants/packages: drop duplicate 'all getters callable' describe
  (individual per-getter tests already cover this)
- packages/normalize: document why the test imports dist/ (bundler
  interop for normalize-package-data CJS wrapping)

Docs:
- environment.md: isTest() now documents VITEST / JEST_WORKER_ID checks
- environment.md: getHome() documents built-in USERPROFILE fallback;
  4 code examples dropped the redundant manual Windows fallback
- http-utilities.md: httpDownload returns all 6 HttpDownloadResult
  fields (not just path + size); destPath is 'recommended absolute'
  not 'must be absolute'

 **Problem:** Path doesn't work on Windows/Unix.
