Tianyi Cui c4647a8609 test: adopt execa for hand-rolled subprocess plumbing, parseArgs for llm-mock-server CLI, vi.waitFor for poll loops
Implements the execa Agent Note's four sub-changes:
- execa (root devDep + loader-smoke dep) replaces the hand-rolled
  spawn-collect-timeout choreography in loader-smoke, apps/cli and
  cli-demo/acp-demo built-bin e2e, lsp-local and code-runtime-worker
  built-lib e2e, the tui pty-harness outer collector, the jsonrpc
  keyless smoke, and crash-recovery's child spawn. Genuinely custom
  parts stay custom: cli-demo's interrupt-on-marker, jsonrpc's
  line-predicate protocol driving, crash-recovery's SIGKILL-at-failpoint.
  The two loader-smoke /* v8 ignore */ OS-error branches are gone.
- llm-mock-server CLI tokenizes via node:util parseArgs; numeric
  coercion/bounds/cross-option constraints stay manual; pinned
  error-message tests updated to the parseArgs texts.
- both loadRootEnv copies in apps/web/tests are deleted: the owning
  vitest configs (web unconditionally, snapshot in record mode)
  already load the repo-root .env before these files run.
- the four poll loops (acp-snapshot harness waits + crash-recovery
  waitForFile) ride vi.waitFor with explicit {interval, timeout}.

code-runtime/ — code-execution capability family

English | 中文

The code-execution capability seam (see capability seams): an abstract runtime interface for executing one model-written program against host-provided async bindings, capturing what it printed and returned. The consumer is the tool registry's Code Mode (tools: { mode: code } — the run_code tool and the generated TypeScript SDK); design in the Code Mode Agent Note. Product packages.

Package Role ctx key
code-runtime/ Abstract code-execution seam (interface + vocabulary) ctx.codeRuntime
code-runtime-worker/ Worker-thread backend: fresh worker per run, TypeScript via host-side type-strip (annotations advisory, never type-checked), port-bridged bindings, budget/heap containment registers ctx.codeRuntime

The interface lives at code-runtime/code-runtime/; the shipped backend at code-runtime/code-runtime-worker/. Backends differ by execution substrate (worker thread, process, container) and by source language — both readonly descriptors on the service — and register ctx.codeRuntime without touching the interface or its consumer; that split is what makes a hardened backend a drop-in later.
