* feat: implement Phase 1 E2E testing with cross-platform CI matrix
- Add shared runCLI helper in test/helpers/run-cli.ts for spawn testing
- Create test/cli-e2e/basic.test.ts covering help, version, validate flows
- Migrate existing CLI exec tests to use runCLI helper
- Extend CI matrix to bash (Linux/macOS) and pwsh (Windows)
- Update Phase 1 tasks and proposal with implementation status
* fix: correct YAML syntax in CI workflow diagnostics command
* fix: use multiline YAML for diagnostics command
* fix ci
* fix: ci
* fix: update core validation and json converter
* chore(ci): split pr and main workflows
* refactor: simplify CI workflow with unified matrix strategy
- Consolidate test_pr and test_matrix into single test job
- Add proper shell configuration with defaults
- Add timeout protection (15 minutes)
- Simplify required-checks to single job
- Maintain cross-platform testing (bash on Linux/macOS, pwsh on Windows)
* fix: restore lean PR workflow with async main branch matrix
- PRs run only essential tests on ubuntu-latest (fast feedback)
- Main branch runs full cross-platform matrix asynchronously
- Separate required-checks for each workflow type
- Different timeouts: 10min for PR, 15min for matrix
