INTcoin v1.1.0-stable

Feature release. One consensus rule change (IIP-0122 minimum fee
floor, activates at mainnet/testnet/signet height 100,000) and one
P2P wire-format reduction (IIP-0209 bloom filters + IIP-0211
REJECT silently dropped at the inbound dispatcher, legacy peer
interop preserved on every other path).

Highlights:
- Lightning Network protocol layer integrated, build-gated off by
  default (-DLIGHTNING_NETWORK=ON to enable)
- Wallet ghost-coinbase scrub self-heals the post-resync phantom
  UTXO bug class
- V2 post-quantum transport AWAITING_KEY tightened: malformed
  Kyber payloads rejected at framing boundary
- Discord backlog sweep closed 26 of 27 reported bugs

IIP-0426 AEAD-for-ISMS migration deferred to v1.2.0 explicitly --
landing two validation-critical wire-format changes (AEAD +
IIP-0122 consensus) in one release was judged too high a release-
engineering risk.
