NI0317 a7bfade7eb refactor(pty): rename model-facing tools to terminal_* and harden teardown
Rename the six model-facing tools pty_* -> terminal_* and align every
description, guidance section, ACP card title, and rendered result to
terminal terminology. Package and service internals keep their technical
PTY names (PtyService, "unknown PTY session", node-pty).

Harden the local backend teardown:
- a failed close is retryable: drop the memoized rejection so a later
  terminal_close re-runs against the live process table
- service disposal clears the backend, reservation, and owner-cleanup
  registries even when a close fails
- stop readiness polling before teardown so an in-flight send settles as
  session_exit instead of a mis-inferred wait reason
- bound the sanitizer's pending buffer against unterminated escape runs

Update the tool catalog, package READMEs, the bilingual Agent Note, and the
acp/headless pty-tools snapshots to match.

pty/ — persistent PTY capability family

PTY stands for Pseudo-Terminal(伪终端). This capability provides persistent, owner-scoped terminal sessions for workflows that require state across tool calls or interactive stdin. PTY complements the one-shot bash and filesystem tools; it does not replace their stronger per-operation contracts.

Package Role ctx key
pty (@deepseek-ai/dsh-pty) Backend registry, branded ids, exact-Agent ownership, session operations, and awaited cleanup ctx.pty
pty-local (@deepseek-ai/dsh-pty-local) Local node-pty backend, readiness detection, bounded terminal state, sandboxing, and process-session supervision registers on ctx.pty
tool-pty (@deepseek-ai/dsh-tool-pty) Six model-facing tools and generic task integration for background sends registers on ctx.tools

The design and deferred boundaries live in the persistent PTY Agent Note.
