docs: sweep every head and profile-dimension number to the live roster

Prompted by a fair question — "don't we have more heads now?" — which turned out to be pointing at
a genuinely ambiguous line. Two different numbers had been drifting:

  195  trained heads       6 taste + 172 aroma + 5 mouthfeel + 12 safety
  183  profile dimensions  6 taste + 172 aroma + 5 mouthfeel  (tox EXCLUDED, deliberately)

Tox is kept out of the flavour-profile vector on purpose: safety is not a flavour-match dimension,
and if it were in there two molecules could rank as "similar tasting" partly because they share a
liver-toxicity signature. That is wrong in a formulation tool and dangerous in a food one.

The stale numbers were spread across the schema, six docs and three source files — 175/177/178-dim
profiles and 166/167-head rosters, each correct at some point in the last two days. The pgvector
column was the worst of them: vector(177) would have rejected every insert of a 183-dim profile at
runtime, and nothing would have caught it until the first real docker compose up.

Also corrects a comment in predict.py that was not merely stale but actively wrong. It claimed the
model load "is fanned out across cores (joblib.load releases the GIL)". Both halves are false —
unpickling is GIL-bound, which is why threads measured ~2.5x SLOWER, and the process pool that IS
faster deadlocks because loading runs during module import. Anyone optimising from that comment
would have re-walked the exact path #225 documents as a dead end.
