test: add comprehensive spinner method tests

Add 45 tests covering spinner methods:
- Core methods: start, stop, clear, text getter/setter
- Status methods: success, fail, info, error, done, step, substep, debug, log
- AndStop variants for all status methods
- Indentation: indent, dedent with chaining
- Progress tracking: progress, progressStep with edge cases
- Method chaining patterns

Coverage improved:
- spinner.ts from 34.43% to significantly higher
- Code coverage: 75.28% (up from 73.63%, +1.65pp)
- Cumulative: 85.99% (up from 85.16%, +0.83pp)

All tests pass (102 test files, 4751 tests)
