Tianyi Cui 3672cd25b4 feat(subprocess): migrate lsp-local, subagent-acp, and the env scrubs onto the seam
Review direction (tianyicui, PR #660): in a stacked PR, change all other
process-running places to use the new service.

- lsp-local: LspConnection spawns through ctx.subprocess (piped protocol
  streams + a no-spill collected stderr tail); its private process-tree
  helpers (POSIX group signalling, Windows taskkill, liveness polling) are
  deleted in favor of the seam's handle verbs, and its buildChildEnv now
  rides scrubbedParentEnv (LSP children also stop inheriting stale DSH_*).
  The plugin injects 'subprocess'; compositions/tests mount
  dsh-subprocess-local.
- subagent-acp: the ACP child spawns through the seam (piped ndjson streams,
  inherited stderr); spawn failure surfaces through done-rejection into the
  same startup race; disposal is handle.dispose with the plugin's configured
  graces. dsh-subagent-subprocess is DELETED — its dispose ladder and scrub
  are the seam's, and the isolated-config-dir helper had no consumer.
- mcp-client, pty-local, sdk-helper: adopt scrubbedParentEnv as the one
  scrub definition (their spawns stay put by ownership: the MCP SDK and
  node-pty own those calls; the SDK wizard runs outside any composition).
- Coverage: per-file 100% over every touched src file, with each v8 ignore
  carrying a platform or contract reason; new suites cover stdio
  dispositions, the dispose ladder tiers, injected-win32 tree semantics,
  waitForExit, settled-kill/terminate no-ops, and spawn-failure disposal.
- Docs: consumer-migration Agent Note (en; zh follows in this PR), seam note
  updated in place, subprocess.md rewritten for the reshaped vocabulary
  (type-equiv re-registered), READMEs and SERVICE_ROLES updated, taskkill
  added to knip ignoreBinaries.

bash/ — bash capability family

The canonical three-package capability seam (see capability seams): an abstract executor interface, concrete implementations, and the model-facing tool that consumes it. All product packages.

Package Role ctx key
bash/ Abstract bash executor seam (interface + vocabulary; sandbox result facts carry the sandbox/ seam's mode/enforcement vocabulary, and the managed-env/output vocabulary is re-exported from the subprocess/ seam) ctx.bash
bash-local/ Local BashExecutor implementation over the subprocess/ service (command defaulting, deadlines, terminal env, background-read merge) (registers ctx.bash)
bash-sandbox/ Sandbox-consuming BashExecutor (wraps every command argv via ctx.sandbox, stamps denial/enforcement facts; extends bash-local's mechanics) (registers ctx.bash)
tool-bash/ Model-facing bash schema; background processes register with the generic tasks/ runtime (registers on ctx.tools)

The interface lives at bash/bash/. bash-sandbox replacing bash-local without touching the interface or the tool is the split doing exactly what it exists for — a leaf cordis.yml picks one executor entry, plus a ctx.sandbox provider entry for the confined one (see the acp-agent example's default composition).
