fix: skip PlaywrightCheck constructs and check files during pw-test [RED-155]

When pw-test runs, PlaywrightCheck constructs defined in .check.ts files
should not be loaded — they interfere with the ad-hoc Playwright test run
by adding a second check and clobbering dependency resolution.

Two changes in parseProject() when currentCommand === 'pw-test':
1. Filter PlaywrightCheck instances from checklyConfigConstructs
2. Skip loadAllCheckFiles() entirely
