dgb: G3b FULL PASS — dual-path won-block leg on genuinely taproot-ACTIVE regtest - #535

…IVE regtest Composes the two already-proven G3b harnesses to close the milestone integrator named as the actual G3b PASS: a c2pool-dgb-assembled won block must reach the network via BOTH the embedded P2P on_block_found path AND the submitblock RPC fallback, run on a net where taproot reached ACTIVE through GENUINE BIP9 signaling (not the regtest always-active default). PHASE 1 reuses the #534 anti-cheat activation (-vbparams genuine BIP9 window; stock 108/144 threshold/window untouched): S0 taproot DEFINED at genesis, defined->started->locked_in->active driven by mined bit-2 blocks, lock-in count asserted >= the stock 108 threshold. PHASE 2 reuses the #458 segwit won-block assembly: a witness-bearing tx is driven through the c2pool-dgb won-block path; the won block must carry the BIP141 coinbase commitment and be ACCEPTED by peer node B. Run twice — ARM A (embedded P2P on_block_found) and ARM B (--no-p2p-relay -> submitblock RPC fallback) — to close the dual-path gate. New assertions beyond #458 (E/G): the accepting peer enforces ACTIVE taproot consensus (getdeploymentinfo taproot.active=true) at the won-block height, so the block is provably valid under real active-taproot rules. Fenced/additive: scripts/ only. No consensus, shared-base, build.yml or CMake surface. Per-coin isolation: DGB only, localhost, self-service creds, ports outside the bitcoin-family regtest band.

Fenced/additive:
scripts/only. No consensus, shared-base, build.yml or CMake surface. Per-coin isolation: DGB only, localhost, self-service creds, ports outside the bitcoin-family regtest band. Composes #534 (activation) + #458 (segwit won-block assembly); FAILS on a pre-#82 binary (ARM B stub) or non-activated net (E/G).No self-merge — integrator merges on operator push approval.
