## Title

    Proposed fix: [Playwright] 'Executable doesn't exist at .../ms-playwright/chromium-NNNN/...' — browsers not installed for this Playwright version

## Body

    Recommended action: Run the install command for the same Playwright version used at runtime (`npx playwright install`, `python -m playwright install`, `pwsh bin/Debug/netX/playwright.ps1 install`); in Docker, pin the mcr.microsoft.com/playwright image tag to the exact project version.
    
    Option: Install browsers matching the runtime Playwright version [evidence: official_recommended_action]
    Applies when: All bindings
    Steps:
    1. Check the installed playwright package version
    2. Run `npx playwright install --with-deps chromium` (or python -m playwright install) with that same version
    3. In Docker, use mcr.microsoft.com/playwright:v<same-version>-noble
    Expected: Launch finds executable
