Command-global bounded-memory failure remains independently

The focused `directory_test_trailer_starts_on_new_line` observer generates
empty, already terminated, and unterminated combined captures. Across both
stages it covers stdout success, stderr failure, signal termination,
concurrent products, filtering, listing, running retention, retained artifact
bytes, and the raw/manual routes that have no coordinator trailer. It requires
complete concurrent stdout/stderr parity and forbids both an adjacent trailer
and a doubled separator.
