test(landing): fix six stale e2e specs and wire the suite into CI (#572)

The landing Playwright suite ran in no CI workflow, so six specs had drifted red on main. Five subpages navigation tests asserted bare paths while the site emits trailing-slash URLs (format: directory), and one asserted a localized tool-detail page that is English-only by design. Fix the assertions and rewrite the tool test to the real invariant, then add a test-e2e-landing job gated on a new landing path filter so the suite runs on landing-relevant PRs and can't silently rot again.
