jest: exclude .test-dir/ from test discovery

dscho · dscho · commit bfa3684b41f2 · 2026-03-04T09:00:18.000+01:00
When a previous test run leaves stale files inside .test-dir/ (e.g. copies
of the real worktree after a corrupted run that operated on the wrong
repository), Jest would discover and attempt to run .test.ts files found
there, producing confusing ENOENT failures. Tell Jest to ignore .test-dir/
entirely.
