docs: align CLAUDE.md + PROVEN-INTEGRATION.md to current state

Replace stale "105 provers" with "128 provers", update ReScript→AffineScript
migration framing, point readers to the new ARCHITECTURE.md / PROVER_COUNT.md
/ ENV-VARS.md / HANDOVER-INDEX.md docs and remove the "ALL IMPLEMENTED"
boast from the prover-support heading (which was tier-1 status, not the
full surface).
