fix: make worker enhancements backward compatible with all test suites

- Made feature name display conditional (only in workers mode)
- Preserved run-multiple process format [X.suite:browser]
- Updated test expectations to match new enhanced format
- All test suites now passing (221 runner + 477 unit tests)

Changes:
- lib/output.js: Conditional feature names + run-multiple detection
- test/unit/output_test.js: Updated worker badge test expectation
- test/runner/run_workers_test.js: Updated 3 test expectations

Fixes #5234
