fix: add tests for CLI-SC/CLI-WD fixes and update stale comments in app.ts

- Add 3 tests for bare span ID detection (CLI-SC): ContextError type,
  error message content, and dash-formatted span ID handling
- Add 1 test for middle-component platform matching (CLI-WD):
  javascript-cloudflare → node-cloudflare-pages/workers
- Update two comments in app.ts that referenced 'events' as an
  unrecognized token — now a registered route after CLI-QZ fix
