Fix --exclude to use substring matching for fixture names

The --exclude flag previously required exact fixture names (e.g.
"clickbench_hits_1k.vortex"). Now it matches substrings, so
"--exclude clickbench" correctly excludes clickbench_hits_1k.vortex.

Validated full round-trip: generate -> check with all 6 synthetic
fixtures passing in both exact and subset modes.
