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}.

lsp/ - LSP capability family

English | 中文

The language-server capability seam: an abstract LSP interface, a generic stdio provider, and the model-facing lsp tool. All product packages.

Package Role ctx key
lsp/ Abstract LSP seam (provider registry by branded id + extension mapping, per-query selection, vocabulary, LspError) ctx.lsp
lsp-local/ Generic multi-server local backend (spawn, JSON-RPC, transient-open queries) (registers providers on ctx.lsp)
tool-lsp/ Model-facing lsp tool (four operations, one-based UTF-16 cursor coordinates) (registers on ctx.tools)

The interface lives at lsp/lsp/. The seam exposes exactly four semantic operations — goToDefinition, findReferences, goToImplementation, hover — and no generic JSON-RPC escape hatch, so a provider swap does not change how the model asks for navigation and no protocol payload or unreviewed mutation reaches the model contract. Providers register capabilities, not tools; tool-lsp is the only owner of the model-facing name, schema, prompt guidance, and presentation.

See the LSP capability seam Agent Note for the design rationale, including why documents open transiently per query, why the local host reads through Node APIs rather than ctx.fs, and why extension ownership is exclusive within one runtime.
