Add durable per-swap actionable state so in-flight swaps survive restarts. Introduces PersistedSwap (borsh-serializable) and a SwapStore trait in the data crate, and a redb-backed DbSwapStore implementation (swaps table) in storage. EVM and Kaspa buffers now load persisted commitments/scripts/pending claims/refunds on connect and persist changes via persist_swap when events mutate state. Kaspa captures and persists funded redeem scripts and prefers stored scripts when spending; EVM added on-chain prechecks (including secret hash/timelock checks) before submitting claims. Plumbing added through ChainDataSink/Node/build_buffer to pass an optional SwapStore. Also adds borsh/hex deps where needed and includes unit tests for the persistence behavior.

Mainly two buckets:
So overall this PR is the first full cut of the cross-chain swap stack, followed by a small formatting/CI cleanup pass. |
