This is a large sync against upstream lnd, bringing BOLT 12 offers, onion messaging, production Taproot channels, and RBF-based cooperative close, alongside the walletd/neutrino Start(ctx) API migration and several fixes from this cycle's review.

Highlights

BOLT 12 (new)

• Offer and InvoiceRequest message structs with TLV codecs and full BOLT 12 reader/writer validation.
• NewInvoiceRequestFromOffer for building a request from an existing offer.

Onion Messages (new)

• Actor-based onion message forwarding with a token-bucket rate limiter and an LRU-cached SCID resolver.
• BFS pathfinding for onion messages, blinded-path support, and a --protocol.no-onion-messages flag.

Taproot Channels (production)

• Production Taproot channel negotiation, gated behind explicit negotiation and rejected for public channel opens.
• Commitment generation, HTLC resolvers, and the nursery all integrate production Taproot support.

RBF Cooperative Close

• A dedicated RBF close actor decouples RPC-driven fee bumps from the peer actor.
• Cooperative close now insta-dispatches CLOSED_CHANNEL on first confirmation instead of waiting.

Channel State Refactor

• Channel state, commitment, forwarding-package, and revocation-log storage moved behind a new chanstate.Store interface.
• Closed channels on KV-SQL backends are now tombstoned instead of bulk-deleted.

RPC

• DeleteForwardingHistory and SubmitPackage (v3 CPFP package relay) RPCs and CLI commands.
• Removed the deprecated SendPayment, SendToRoute, and TrackPayment RPCs (routerrpc V2 equivalents remain).

Fixes

• chain.Interface.Start now takes a context.Context, matching the same change in walletd/flokicoin-neutrino.
• Fixed a panic in the DNS fallback SRV lookup; RPC handler panics are now recovered.
• BOLT-02 push_msat bound is now enforced on the fundee.

Dependency Security

• Bumped golang.org/x/crypto to v0.52.0 and google.golang.org/grpc to v1.79.3, closing GHSA-p77j-4mvh-x3m3 (a gRPC authorization-bypass advisory) among others.
