Expand description

Prune fingerprint-specific Cargo target directories under target_dir.

Pruning uses the same exclusive process lock as builds. Entries older than the configured age are removed first, then least-recently-used entries are removed until the configured logical byte limit is met. Only direct child directories with SHA-256 fingerprint names are eligible; caller-facing artifacts and unrelated target contents are never removed.
