TASK-35	Add CI/CD pipeline for automated testing and quality gates	To Do		2026-02-14 00:57	infrastructure ci quality		high

Description

Add a GitHub Actions CI pipeline that runs on PRs and pushes to main. The project already has 23 test files (67+ tests) and a check-main-lines.sh quality gate script with progressive line-count targets, but none of this runs automatically.

Motivation

Without CI, regressions in tests or quality gate violations are only caught manually. As the refactoring effort (TASK-27.x) accelerates and new features land, automated checks become essential.

Scope

1. Test runner: Run pnpm test on every PR and push to main
2. Quality gates: Run check-main-lines.sh to enforce main.ts line-count targets
3. Type checking: Run tsc --noEmit to catch type errors
4. Build verification: Run make build to confirm the app compiles
5. Platform matrix: Linux at minimum (primary target), macOS if feasible

Implementation notes

• The project uses pnpm for package management
• Tests use Node's built-in test runner
• Build uses Make + tsc + electron-builder
• Consider caching node_modules and pnpm store for speed
• MeCab is a native dependency needed for some tests — document or skip if unavailable in CI

Acceptance Criteria

• #1 GitHub Actions workflow runs pnpm test on every PR and push to main.
• #2 Quality gate script (check-main-lines.sh) runs and fails the build if line count exceeds threshold.
• #3 tsc --noEmit type check passes as a CI step.
• #4 Build step (make build) completes without errors.
• #5 CI results are visible on PR checks.
• #6 Pipeline completes in under 5 minutes for typical changes.
