fix: Correct branch references from main to master

The default branch is still master, but several files referenced main,
causing docs deployment and coverage badge pushing to silently fail.

Fixed references in:
- CONTRIBUTING.md: branch instructions
- docs/contributing.md: branch instructions
- docs/index.md: coverage badge URL, LICENSE link
- README.md: coverage badge URL
- .github/workflows/test.yml: git-token condition
- .github/workflows/docs.yml: branch trigger
