feat: support for aptos

[frolvanya]

Add Aptos chain support

Adds Aptos as a supported chain to the omni-relayer, following the same MPC-proof-based finalization pattern used by Starknet.

What's included

New worker (omni-relayer/src/workers/aptos.rs): handles all three event types —

• process_init_transfer_event — finalizes inbound Aptos→NEAR transfers using NearFinTransferWithMpcProof
• process_fin_transfer_event — claims relayer fee using ClaimFeeWithMpcProofTx
• process_deploy_token_event — binds token metadata using BindTokenWithMpcProofTx

Indexer types (bridge-indexer-types): adds AptosTransaction origin, AptosInitTransferMessage, AptosFinTransferMessage, AptosDeployToken, and AptosLogMetadata to the shared document types.

Config: new optional [aptos] section with rpc_http_url and omni_bridge_address; relayer account address read from APTOS_ACCOUNT_ADDRESS, private key from APTOS_PRIVATE_KEY.

Dependency updates: bumps omni-types and all bridge-sdk-rs crates to revisions that include Aptos support (aptos-bridge-client added).

Known limitation

MPC finality is not currently wired to the EVM and Starknet bridge clients (it was previously). This is caused by a diamond dependency conflict: omni-types pulls near-mpc-contract-interface from crates.io while the new bridge clients pull it from git, making the MpcFinality type incompatible at the crate boundary. The clients fall back to their safe default finality thresholds — behavior is correct, just not optimized. This will be restored once the upstream near/mpc dep is published to crates.io or the workspace is unified.

Pre-existing fixes (incidental)

• native_indexers/solana.rs: FinTransfer::Solana and DeployToken::Solana were missing the chain_kind field
• native_indexers/evm.rs: ChainKind::Fogo was missing from the non-EVM bail arm

Testing

Upstream PRs this depends on:

• bridge-sdk-rs feat: support for aptos bridge-sdk-rs#294 — aptos-bridge-client crate
• omni-bridge feat: Aptos support omni-bridge#626 — Aptos in omni-types

[frolvanya]

mpc_finalities are dropped for now, because of dependency conflict. Out omni-types use near-mpc-sdk v0.0.1, when I set it to updated version that knows about AptosFinality, it requires our omni-bridge to use near-sdk-rs v5.28.0+, but this version already requires rustc v1.88.0+, but mainnet is not updated yet to support contract compilation with rust version higher than 1.86.0

Pull request overview

This PR adds Aptos as a supported chain in omni-relayer, following the existing MPC-proof-based finalization flow already used for Starknet. It also updates the shared bridge-indexer-types event/document schema to represent Aptos-origin transactions and messages, and bumps bridge-sdk-rs / omni-types revisions to pick up Aptos support in the SDK. Additionally, it introduces a GitHub Actions workflow + scripts/prompts for automated Claude-based PR review.

Changes:

• Add an Aptos worker and wire Aptos init/fin/deploy event handling through the relayer pipeline (including config/env plumbing).
• Extend bridge-indexer-types to include Aptos transaction origins, transfer messages, and meta events.
• Update dependencies (bridge SDK + omni-types) and add a Claude PR review workflow + helper script/prompt.
