Cover the real-world grep usage shapes from the tldr page end-to-end through uumain over a shared multi-MB corpus (plus a directory with a binary file for -rI): search pattern, -F fixed string, -rI recursive ignoring binary, -C 3 context, -Hn --color=always, -o only-matching, -v invert, -Ei extended + ignore-case. Kept alongside the pure-scan throughput benches (literal vs regex, no match). A rare marker keeps matched output small so the full-file scan dominates the timing.
