These are non-trivial untested impls. I'm not saying the previous approach was better, but it doesn't seem fantastic to copy-paste these here either.

Motivation
TXE only used
AztecNodeServiceas a read-only facade over its own archiver and world state, yet the dependency pulled the whole server stack (p2p, sequencer, validator, prover, slasher, epoch-cache, ethereum) into its graph, plus ~400 lines of fakes whose only purpose was satisfying the node constructor. Decoupling TXE from the node also removes a blocker for splitting the repo, where TXE lands on the client-tooling side.The change
TXENodeserves the read-side queries the PXE services actually call (blocks, membership witnesses, logs by tags, tx receipts, contract data, public storage) directly overTXEArchiverandTXESynchronizer. It extendsUnimplementedAztecNode, a full transcription of theAztecNodeinterface whose methods throw, so any surface the TXE does not cover fails loudly.DummyP2P,MockEpochCacheand the TXE global-variable/fee builders; dropped the@aztec/aztec-nodeand@aztec/bb-proverdependencies along with the esbuild stubs that existed only to neutralize the node import graph in the TXE bundle.getContractaccepts block-hash reference parameters.proven/finalized) matchesgetL2Tipsinstead of resolving to genesis.
