chore(release): bump versions for v1.12.0

[slin1237]

Description

Problem

139 commits have landed since v1.11.0. The crates workflow has no tier for the two crates #2727 added, engine-zmq-adapter and engine-servicer, and smg depends on both (the adapter as a dependency, the servicer as a dev-dependency), so the final-tier publish of smg would fail on crates.io. And smg-grpc-servicer 0.13.2 on PyPI predates #2878 and #2879, the two SGLang 0.5.21 fixes to the Python servicer (valid sampling defaults in the gRPC warmup, health signals on the tokenizer socket).

Solution

Apply the version bumps the release checker proposes against v1.11.0 with VERSION_OVERRIDE=1.12.0, refresh the workspace pins and Cargo.lock, add the two crates to the crates workflow as tiers 3 and 4 with smg moving to tier 5, and bump the servicer so the gRPC PyPI workflow republishes it.

Changes

• smg 1.11.0 → 1.12.0, and the same version for the Python and Go bindings, the Helm chart (version and appVersion) and the four engine Docker release workflows (TokenSpeed's included now that ci(release): build the TokenSpeed image against SMG v1.11.0 #2676 registered it with the checker).
• Independently published crates, by detected change level: openai-protocol 1.15.0, reasoning-parser 1.9.0, tool-parser 1.9.0, llm-tokenizer 1.9.0, kv-index 1.6.0, llm-multimodal 1.13.0, smg-grpc-client 1.14.0, engine-zmq-client 0.3.0, smg-external-router 0.2.0. The two new crates publish at their initial 0.1.0. smg-symphony is publish = false and nothing published depends on it.
• Workspace Cargo.toml dependency pins and Cargo.lock updated to match (cargo update -w --offline, 12 entries).
• .github/workflows/release-crates.yml: tier 3 becomes a matrix of llm-multimodal and engine-zmq-adapter (its workspace dependencies are engine-zmq-client and openai-protocol in tier 1, smg-grpc-client and llm-tokenizer in tier 2); a new tier 4 publishes engine-servicer (engine-zmq-adapter plus tier 1 and 2 crates); smg moves to tier 5. The other tiers are unchanged since v1.11.0 verified them.
• smg-grpc-servicer 0.13.2 → 0.13.3. Its smg-grpc-proto>=0.4.24 floor is unchanged: 0.4.24 on PyPI is current, since the proto's last bump landed with its last change in feat(router): support Decisions over SGLang gRPC #2867. Merging triggers the gRPC PyPI workflow.

On the ! commit

feat(discovery)!: tagged discovery config with one runtime conversion (#2833) changes the Rust API of the smg crate: DiscoveryConfig is a tagged enum, ServiceDiscoveryConfig.enabled is gone, and ServerConfig.service_discovery_config is an Option<RuntimeDiscoveryConfig>. The checker maps that marker to a major bump and proposed 2.0.0. This release ships it as a minor on purpose, as v1.11.0 did for #2532: CLI flags, Python arguments, serialized configs and the Helm chart all keep working (--service-discovery stays as the legacy spelling of --discovery-provider kubernetes), crates.io lists no reverse dependencies of smg, and the in-repo Python binding was migrated in the same change. The release notes carry the migration table for anyone building on the crate directly.

Test Plan

• make check-versions TAG=v1.11.0 VERSION_OVERRIDE=1.12.0 reports every crate bumped and ends with "All versions consistent."
• cargo update -w --offline produced the 12 Cargo.lock version updates in this PR; cargo metadata --locked resolves.
• rustup run nightly cargo fmt --all -- --check and git diff --check clean (no Rust source changed). The publish workflow parses, with the needs chain tier1 → tier2 → tier3 → tier4 → tier5.
• No 1.11.0 reference remains outside Cargo.lock history.
• PyPI inspected: smg-grpc-servicer 0.13.2 and smg-grpc-proto 0.4.24 are the latest; the servicer's last bump (feat(router): support Decisions over SGLang gRPC #2867) predates fix(sglang): send valid sampling defaults in gRPC warmup #2878 and fix(sglang): handle health signals from the tokenizer socket #2879, which change sglang/request_manager.py and sglang/server.py.
• Rust 1.98.0 (CI's pin) on macOS: cargo clippy --workspace --all-targets -- -D warnings stops in kv-index's mooncake_replay bench on Linux-only libc symbols (clock_nanosleep, cpu_set_t), as it does on main; cargo test stopped at llm-multimodal's parallelism_pool integration test, which expects the preprocessing pool to name three threads and finds none on macOS (the Linux-only test assumptions feat(router): support Decisions on the regular HTTP router #2863 and feat(router): support native System One API #2865 note); 21 test binaries before it passed. A --no-fail-fast run of the whole workspace on 1.98: 170 test binaries, 7,369 passed, 3 failed, 45 ignored. The three failures are macOS-only: parallelism_pool counts threads through /proc/self/task, and the two allocator_artifact_test cases check that jemalloc applied the executable's embedded malloc_conf, which this platform's jemalloc does not take (feat(kv_index): the chain index, a lossless KV-event relay with state snapshots, and liveness-aware cache routing #2814 validated them on Linux). This version-only PR changes no Rust source, so the Linux CI lanes are the gate.

Merge Risk: 🔵 Low · up to 8c2e5

This release changes only versions and release configuration. Rust projects that depend on the smg crate as a library may get the new Rust API through an ordinary 1.x update and fail to build. Merging is reasonable if maintainers accept that tradeoff and document the migration; otherwise, publish this crate under a major version.
