zeekayandGitHub be243c56d7 bridgevm: promote quote engine + swap store from cmd/bridge daemon (#3)
The bridge is permissionless and non-custodial. Authoritative quote
math and swap state must live where the validator quorum runs
consensus — in this VM — not in any single daemon's local cache.
This change moves both into bridgevm and exposes them via JSON-RPC
so any client can reach the same settlement decisions.

New RPC methods:
  bridge_estimateFee     — authoritative quote computation
  bridge_submitRequest   — create + quote-snapshot
  bridge_getStatus       — read swap by id
  bridge_cancelRequest   — idempotent cancel
  bridge_health          — liveness probe
  bridge_getMPCPublicKey — threshold group public key

Architecture:
  - QuoteEngine     (quote.go)         StaticPriceFeed → quorum oracle later
  - SwapStore       (swap_store.go)    in-memory genesis impl; block-persistence next
  - Service methods (rpc.go)           JSON-RPC dispatch (snake + dot aliases)

Attestation aggregation already lived in bridge_signing.go via
BridgeSigner + BridgeMessageValidator — no changes needed there.

LP-333 signer-set methods unchanged.
