Receiving BOLT12 payments in LND
summary
Claims a working shim that runs LNDK next to LND to enable full BOLT12 offer/receive flows today, using onion messages, blinded paths and standard TLVs; demo creates an offer, selects three peers to build a blinded path of three hops, sends an invoice-request onion, receives a blinded invoice and pays it successfully. Key tricks: stateless seed via LND sign (inspired by BIP50) so restarts need no DB, 100 ms batching for forwards, and an internal rate limiter to mitigate DoS. LDK 0.3 support and full BOLT12 structures are implemented.
