The kvdb-to-SQL data migration polls lnd's ListMacaroonIDs RPC, which only becomes available once lnd reaches its "RPC active" state. On nodes with a large channel/graph state, lnd can take well over a minute to get there after the wallet is unlocked, which exceeded the previous fixed 60-second (120 x 500ms) poll budget and caused the migration - and therefore litd startup - to fail permanently, requiring a manual restart. Replace the fixed attempt cap with a wait bounded by the new --lndreadytimeout config option, defaulting to a generous 10 minutes, while still aborting early if the daemon is shutting down. The wait happens inside the migration's SQL write transaction, so it is kept bounded rather than unbounded as a safety backstop.
