Subject: [PATCH] dgb(#82): make daemon softfork readiness gate regtest-aware
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The startup readiness gate (NodeRPC::check) requires the full SSOT
SOFTFORKS_REQUIRED set {nversionbips,csv,segwit,reservealgo,odo,taproot}.
A regtest digibyted legitimately deploys only csv/segwit/taproot — the
DGB-specific algo softforks (reservealgo, odo) and nversionbips are
mainnet/testnet deployments not carried on regtest. Gating startup on
deployments the connected chain cannot carry made the regtest won-block
path (and CI against regtest) impossible to start, with no consensus
benefit.

Relax ONLY when chain==regtest; mainnet/testnet keep the full SSOT
requirement set unchanged. Non-consensus startup readiness gate only;
the SOFTFORKS_REQUIRED SSOT and its KAT are untouched.

Verified live: armed run-loop against regtest digibyted now clears the
gate (CoindRPC connected; no Refusing-to-start retry loop), work source
+ Stratum stand up, embedded P2P handshake OK. dgb_share_test 16/16.
