fix: skip node_modules and other ignored directories in test discovery

Repterm's test loader was recursively scanning into node_modules and loading test files from dependencies (like bun-pty), causing fatal errors when describe() was used in contexts where it's not supported. This fix skips common non-test directories (node_modules, .git, dist, .next, .turbo) during recursive test discovery.

Fixes the 'Cannot use describe outside of the test runner' error when running repterm with --record flag.
