test(hermes_cli): keep one opencode-go delisting invariant; record the delisting beside the keyed-suffix set

Drop the floor-pin test from #106290 (a snapshot of the static table); the
end-to-end merge test through provider_model_ids with the real curated floor
already fails if the slug is re-added. Note beside
_OPENCODE_FREE_KEYED_SUFFIX_MODELS why ox-alpha-free stays excluded from the
keyless catalog even though it left the curated floor.
