lock: ogar pin 597ecb1 -> a0c7936 (OGAR #146 — OSINT contributes zero vocabulary rows)

OGAR #146 executed the operator ruling: both #145 OSINT mints removed
(low byte is APPID space domain-wise), ALL back to 65 == the mirror's
65 — the COUNT_FUSE balances with zero mirror-side changes. This
branch's earlier +2-rows + zero-slot carve-out commits were dropped
during the rebase onto main (#626/#627) as superseded by that ruling.
Verified: contract ogar_codebook 8/8 + lance-graph-ogar standalone
green against a0c7936 (compile-time COUNT_FUSE holds).
