Orgchain v1.6: holdings share the mining, every act pays its gas, money crosses holdings

Mining is a lab setting. Split (the default) pays every active holding a
share of each beat, pro rata by a hashrate dial on each holding (0 to 9,
1 unless set), one coinbase output per holding. Last act gives the whole
beat to the holding that acts. Every act is paid by the acting node's own
keys: fees and postage come out of its gas tank (the plain coins at its
Taproot key), which tops up from its own money 0.0001 test BTC at a time.
Each act is checked before anything is signed, so an unfunded node can't
act. A graduating org pays for its own claim, and the lab wallet pays only
for foundings and for holdings that predate lab keys. Sends cross
holdings, the ledger shows gas top-ups, and chain keys are derived once
per page.

The engine's second local change: a coinbase may split its reward across
up to 64 outputs (mineTo), in src/adapters/chain.js.

-One local change to the engine (Orgchain v1.5): `src/adapters/chain.js` also accepts native SegWit (P2WPKH) outputs and SIGHASH_ALL P2WPKH spends, verified per BIP-143, so lineage accounts can hold and send test BTC at their BIP-84 addresses. Everything about inscriptions stays Taproot-only. The change is original code, tested in `tests/money.test.js`; Super Testnet's tests (`tests/adapters.test.js`) pass unchanged.
