chore: untrack .playwright-cli/ debug artifacts + gitignore

The two log files (console-*.log, page-*.yml from 2026-04-11) slipped
into the previous textarea commit via git add -A. They're stale
browser-automation session artifacts, not source. Untrack + gitignore
so future git add -A doesn't grab them again.
