peer: depend on chanstate Store
Replace the peer config's concrete channel state DB dependency with
chanstate.Store. Brontide only needs channel lookups, closed-channel
lookup, and initial forwarding policy access from the channel-state
store.
What changed, and why it matters
This commit is a straightforward internal code cleanup: it swaps a specific database type for a narrower interface in one part of the Lightning Network Daemon (LND). It does not change user-facing behavior, fix a bug, or alter security logic. There is no indication this is a security patch.
No security action needed. Treat as normal refactoring.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change replaces the concrete *channeldb.ChannelStateDB dependency in peer.Config with the chanstate.Store interface. The comment is updated accordingly. This is an interface-abstraction refactor that limits the peer/brontide package’s required surface from the channel-state store to lookups and forwarding-policy access. No functional or security-relevant logic is modified.
