perf(ci): add path filters to skip CI for non-business logic changes

Add comprehensive path filters to only trigger CI when files that affect
functionality change:

Included paths:
- Rust source (*.rs) and config (Cargo.toml/lock, build.rs)
- JavaScript/TypeScript (*.js, *.ts, *.jsx, *.tsx, *.mjs)
- Frontend assets (*.html, *.css)
- Node.js config (package.json/lock, tsconfig, vite/vitest/playwright)
- Tauri config (tauri.conf.json)
- Task runner (taskfile.yml, taskfiles/**/*.yml)
- Test files (tests/**/* and **/tests/**/*)
- CI workflow itself (.github/workflows/test.yml)

Excluded (won't trigger CI):
- Documentation files (*.md, AGENTS.md, CLAUDE.md)
- Backlog tasks (backlog/**/*.md)
- Dependency audit reports
- Other non-functional changes

This saves CI compute resources by skipping test runs when only
documentation or project management files change.
