chore: improve type coverage (97.43% → 97.46%)

Add explicit type annotations to improve type safety:
- sorts.ts: Add FastSortFunction type to _naturalSorter
- themes/context.ts: Add Theme type to resolvedTheme variables
- spinner.ts: Add explicit types for colors, YoctoCtor, etc.
- objects.ts: Add type annotation for proto variable

Tests: 4,565 passing
