BIP-110 disables OP_IF and OP_NOTIF in tapscript and limits data pushes to 256 bytes. Adds an alternative inscription envelope parser: a bare protocol push followed by a series of data pushes balanced by OP_DROP and OP_2DROP. Matches the envelope shape proposed in ordinals/ord#4545 so we parse the same inscriptions the ord indexer will. Both envelope shapes share the same "ord" push (four bytes); a classic envelope is any occurrence preceded by OP_FALSE OP_IF, anything else is BIP-110. One marker, one scanner, one extractor handles both -- the terminator switches to OP_DROP / OP_2DROP for BIP-110 and the envelope-size math is a single subtraction, no fudge factors. Testing: no BIP-110 shape inscription exists on chain yet, so the spec uses a hand-crafted synthetic transaction (txid = "deadbeef" x 8). The GOLDEN RULE (every test uses real blockchain data) is waived here on purpose: this test pins the wire-format parsing so it works on day one when a real BIP-110 envelope lands. Add a real-tx spec when one exists on mainnet.
