Add Ark <-> Lightning via the ASP (captaind-native submarine swaps)

The ASP is the HTLC counterparty (second.tech's protocol), so no external
swap provider is needed: paying a bolt11 converts pubkey vtxos into
ServerHtlcSend vtxos the server can only claim by revealing the invoice
preimage; receiving grants ServerHtlcRecv vtxos claimed by revealing ours.
Failure paths cosign the HTLC back (revocation) — proven end-to-end against
regtest captaind, which independently derives the HTLC taproots.

- ark/lightning.js: bolt11 decode, lightning fee schedules, all pay/receive
  gRPC-web wrappers (cosign, initiate, status, revocation, hold-invoice
  receive flow, anti-DoS attestation)
- ark/send.js: arkoor builder generalized to policy outputs (pubkey /
  serverHtlcSend / serverHtlcRecv), two-leaf taproot trees, HTLC clause
  scripts, reusable per-part cosign helpers for package RPCs
- ark/manager.js: ln-pay and ln-recv crash-safe action state machines
  (deterministic receive preimages from the seed, chain 5), mailbox
  lightning notifications, unpayable-invoice -> instant revocation
- proto.js: lightning ArkInfo fields + mailbox lightning message decode
- validate/refresh: policy-aware vtxo validation and reconstruction
- features: bolt11 routes via ark when the balance covers it (Boltz stays
  the fallback), lightning-invoice receive on the Ark pane
- tools/ark/ln-test.js: harness proving HTLC cosign + revocation against
  captaind; manager-test.js updated for the consolidated bc-container chain
