adapt to centralized single-sequencer (tendermint v0.3.8 / geth morph-v2.2.4) — integrate #92 + #100

[curryxbo]

Integrates #92 + #100 and adapts run-morph-node to the centralized single-sequencer model.

Version matrix

component	pin
go-ethereum	morph-v2.2.4 (0eda191)
morph	main (f96a4775, single-sequencer network config)
tendermint	v0.3.8 (a5de063) — enters via morph node/go.mod replace, not a submodule/service here
docker: geth	2.2.3 → 2.2.4
docker: node	0.5.7 → 0.6.0

Changes

Single self-verifying node (from #100):

• Remove the separate validator docker-compose service; merge its env into the single node.
• Expose DERIVATION_VERIFY_MODE → --derivation.verify-mode: local (default) / layer1 (former validator behavior).
• run-binary.sh drops the node|validator mode arg.
• Validator role kept as a mode, not a container: make run-validator / run-hoodi-validator (+ -binary) run the same node with --derivation.verify-mode=layer1.
• Keep stop-validator / rm-validator as aliases of stop-node / rm-node for backward-compatible command usage.

Legacy cleanup:

• Remove ZK legacy: .env_zk, .env_hoodi_zk, entrypoint-geth-zk.sh, all run-zk-* / *-zk-snapshot targets, and the ZK README tables.
• .env_hoodi: restore NODE_EXTRA_FLAGS=--hoodi (else node → network=dev and fails "L1 Sequencer contract address is required").
• Align env snapshots/heights to README newest MPT (mainnet snapshot-20260701-1, hoodi snapshot-20260630-1).
• Do not carry WIP:chore: bump morph + geth to derivation-batch-verify; align hoodi snap… #92's WIP test-derivation doc.

Docs/config correctness:

• Correct L1_BEACON_CHAIN_RPC comments: it is required at startup in both verify modes.
• Use the real published morph-main node image tag 0.6.0 instead of the provisional 0.5.8.

Verified

• docker compose config: services = geth, node only; default MORPH_NODE_DERIVATION_VERIFY_MODE=""; validator targets resolve it to layer1 (shell env overrides env-file).
• make -n for all node/validator/binary/quickstart targets → correct invocations.
• All shell scripts parse clean; no dangling refs to removed targets/files.
• Local compile verification passed on darwin/arm64 with go 1.24.13:
  • go-ethereum @ 0eda191 (morph-v2.2.4): make geth → exit 0
  • morph/node @ f96a4775 with tendermint v0.3.8 dep: make morphnode → exit 0

Cross-repo issue morph-l2/morph#989 won't auto-close; close manually if applicable.

✅ Local compile verification passed (go 1.24.13, darwin/arm64):

• go-ethereum @ 0eda191 (morph-v2.2.4): make geth → exit 0.
• morph/node @ f96a4775 (tendermint v0.3.8 dep): make morphnode → exit 0. (Only benign ld macOS-version warnings on the prebuilt zstd static lib.)
• Built morphnode contains derivation.verify-mode (4×) and the --validator → --derivation.verify-mode=layer1 deprecation alias — verify-mode / single-sequencer code is present.

Note: morph pulls geth as a Go module pinned to v1.10.14-...-0eda19148ddd (= morph-v2.2.4), so the build doesn't depend on the nested submodule state.

Remaining before merge: replace provisional node:0.5.8 with the real published morph-main image tag.
