The E2E test "should show script path field when Script type is selected"
was failing because the locator didn't match the actual UI field.
Update locator from /create/i to /script path/i
Update placeholder matcher from /create-dns/i to /dns-challenge.sh/i
Matches actual ScriptProvider field: label="Script Path",
placeholder="/scripts/dns-challenge.sh"
Also includes skill infrastructure for Playwright (separate feature):
Add test-e2e-playwright.SKILL.md for non-interactive test execution
Add run.sh script with argument parsing and report URL output
Add VS Code tasks for skill execution and report viewing
