## Description

---

The private ACP package exports individual RPC definitions and implementation helpers that no repository consumer imports.

Keep those definitions local and remove the unused client `layer` wrapper. The live client factory, child-process layer, agent constructor/layers, and RPC groups remain exported. The agent constructor has a local `@public` explanation because the repository's Effect service convention requires public construction APIs. Generated upstream protocol definitions are untouched.

Verification on the integrated stack:

- ACP Knip export scan passes.
- All 40 existing ACP tests pass.
- ACP typecheck, targeted lint, and formatting pass.

No tests or runtime protocol behavior changed. This is the first cleanup layer; [#10171](https://github.com/pingdotgg/t3code/pull/10171) enforces exports across all seven internal packages.
