build: add Smithers workspace and package definitions

[roninjin10]

What this is

Design-partner configuration for Smithers, a Bazel-like build and agent-workflow system. The @smthrs packages do not exist yet: this is API-driven development, where real repos define the API through usage and the implementation follows. Nothing here runs today.

Tevm is the monorepo design partner. It exercises workspace graphs, a second runtime, Rust crates, multi-registry release, and external test corpora.

Layout

• WORKSPACE.ts — Node and Bun runtime layers, pnpm workspace graph, host binaries.
• Root PACKAGE.ts — lint, cross-package suites via label-pattern queries, changesets release train, JSR publish, emitted GitHub CI (replacing ci/release/jsr-publish/wasm-size-check/parity-suites workflows), coverage and size gates, gated commit/pr targets, nightly conformance cron.
• Per-package PACKAGE.ts — packages/{evm,state,actions,errors,memory-client}, tevm/, cli/, test/, bundler-packages/{vite,resolutions-rs}, extensions/viem, sites/core. Each category has one exemplar file; siblings follow it, noted in comments.
• workflows/ — a JSDoc agent lint and a conformance-triage workflow (EIP-3155 trace-diff loop over the repo's trace tooling).
• smithers.d.ts — permissive ambient declarations so the files type-check until the real packages ship.

API surfaces this repo introduces

• S.Npm.Workspaces / S.Npm.WorkspaceDeps — the pnpm workspace graph as a layer; workspace:* deps resolve to built outputs in topological order, replacing nx dependsOn: ^build with data edges.
• S.Query({ pattern: "//**:test" }) — label-pattern aggregation replacing nx run-many; new packages join suites without imports.
• S.Runtime.Bun — a second runtime as a plain workspace layer key.
• S.Cargo.* / S.Napi.Build — the Rust crates and their napi platform emits.
• S.Changesets.Version/Publish, S.Jsr.Publish — the release train, gated on CI plus a //**:apiCompat query.
• S.Npm.PackageLint — publint + attw against the packed tarball.
• S.Size.Gate, S.Coverage.Gate — byte and coverage floors in the graph.
• S.Git.Checkout — rev-pinned external fixture corpora (ethereum/tests, execution-spec-tests), the http_archive analog.
• sandbox: { docker: true } — admits the host docker daemon for hive.
• S.Vercel.Deploy — the docs site, gated on sample verification.
