feat: support vetiver bridge abi (DX-1812)

[nicov-iov]

Summary

• Adds the new VETIVER Bridge ABI release (bridge-vetiver.json) and registers it in bridgeAbi.js at mainnet height 8804200 and testnet height 7604200.
• Bumps @rsksmart/rsk-precompiled-abis from ^8.0.0-REED to ^9.0.0-VETIVER.
• Adds tests verifying the new ABI decodes both getEstimatedFeesForPegOutAmount(uint256) and the updated getEstimatedFeesForNextPegOutEvent().

Why

Rootstock node (RSKj) introduced a new Bridge method getEstimatedFeesForPegOutAmount(uint256 pegOutAmountInWeis) and updated the semantics of getEstimatedFeesForNextPegOutEvent() (now uses the minimum peg-out value instead of 1 BTC). The parser must recognize and decode these so the explorer correctly displays Bridge interactions.

Test plan

• npm run test:local — 402 passing, including 2 new decode tests for vetiver ABI
• npm run lint — clean
• npm run build — dist/ regenerated and consistent with src/

Notes

• Existing getEstimatedFeesForNextPegOutEvent() selector is unchanged — only semantics updated.
• Version bump for the parser package will happen in a separate release PR per repo convention.

test/bridgeAbi.spec.js:96

• Like the previous case, this encodes and parses with the same ABI, which does not prove the parser recognizes the actual precompile selector for getEstimatedFeesForNextPegOutEvent() after the Vetiver boundary. A fixed calldata/selector fixture would make this regression test independent of the ABI under test.

    const iface = new Interface(vetiver.filter(i => i.type === 'function'))
    const data = iface.encodeFunctionData('getEstimatedFeesForNextPegOutEvent', [])
    const parsed = iface.parseTransaction({ data })
