chore(ci): skip build workflow for non-code changes

Skip linting, building, and testing when only non-code files change:
- Documentation (*.md, docs/)
- Assets (assets/, schemas/)
- GitHub templates (.github/ISSUE_TEMPLATE/)
- IDE/editor config (.idea/, .claude/)
- Git config (.gitignore)
- Commit lint config (.commitlintrc.yml, package.json, package-lock.json)
- Install scripts (install.sh, install.ps1)
- LICENSE

Add new script-lint.yml workflow that runs ShellCheck and PSScriptAnalyzer
when install scripts change.

Commit and PR title linting still runs via commit-lint.yml.
