Have assert-score symlink reports into an out dir on success Add --out-dir to the assert-score subcommand. When set and the assertion passes, the driver creates the directory (if absent) and symlinks report.txt and report.json from the report directory into it. assertMutationScore.nix's buildCommand shrinks to a single subcommand invocation: no mkdir, no ln -s, no Bash glue at all. Tests cover three runAssertScore paths: pass with --out-dir populates the directory, fail aborts before symlinking, missing report.json exits with code 2.
