Journeys 07–10: codegen-consume, interface-consume, protocol-fixture, live-network

[scarmuega]

Fills the journey gaps from the umbrella plan dx-e2e-journeys-remaining, which became the sole real-binary coverage of these surfaces after tx3-lang/trix#129 hermeticized trix's local suite (every tx3c interaction there now runs against a fake).

New journeys

Journey	Covers	Scope
07-codegen-consume	Real tx3c codegen + published codegen-v1beta0 templates → generated ts-client compiles in a host package (npm install + tsc) → resolves a transfer through the generated client against a local devnet TRP	runtime; needs node (skips cleanly if missing)
08-interface-consume	Build a real TII, prime the consumer cache byte-for-byte as trix use writes it, then real tx3c decode via inspect tir (alias + full-ref forms) and codegen-for-interface from the cached TII	compile/lower; offline, no registry
09-protocol-fixture	The acme/hydra-heads production-scale protocol (~1000 lines) through check → build → inspect tir	compile/lower; offline
10-live-network	trix invoke -p preprod --skip-submit against a live Demeter TRP endpoint, mirroring the sdks live-e2e env contract (TRP_ENDPOINT_PREPROD, TRP_API_KEY_PREPROD, TEST_PARTY_A/B_ADDRESS)	secrets-gated; skips green without env

CI changes

• 04-devnet-roundtrip graduates to the stable job: the trix#123 expect fix ships in trix 0.26.2, which is what the stable channel now installs — verified locally (Test Passed). Its README's "add to stable once fixed" trigger has fired.
• 07/08 also join the beta cherry-pick (they're the drift-detectors for the contracts trix#129 stubs).
• New dx-e2e-live.yml: weekly + manual, forwards the four live secrets to 10-live-network. Until those secrets are configured on this repo it's a green no-op (the journey logs the skip).
• pull_request triggers added to the stable/beta workflows — this repo had no pre-merge validation at all (the push-to-main-only triggers predate the extraction).

Verified locally (trix 0.26.2 / tx3c 0.23.0 — the current stable channel)

• Each new journey green in isolation (./run.sh --journey <name> --verbose) and the full suite green: 10 passed, 0 skipped, no leaked dolos daemons.
• Journey 10: skip path green without env; half-configured env fails loudly; the [networks.preprod] override was smoke-tested against the public Demeter preprod TRP (reaches the endpoint; fails only on the unfunded probe address, as expected).

Known findings (tracked umbrella-side)

• No trix test slice in 09: every upstream protocols/ fixture ships a stale scaffold tests/basic.toml referencing a transfer tx none of them define (unknown tx: transfer). The round-trip slice unblocks when the fixtures grow real scenarios.
• Arming 10 needs the TRP_* / TEST_PARTY_* secrets (same values as the sdks repo) added to this repo.
