Depends on #5365

dcode --acp sessions now survive process restarts and can switch among discovered models without losing checkpointed context.

ACP mode now keeps dcode’s SQLite checkpointer open, builds each session for its cwd and selected model, and advertises the installed model catalog through session/set_config_option.

Test plan
  • PYTHONPATH=../acp:../deepagents:. .venv/bin/python -m pytest -q tests/unit_tests/test_main_acp_mode.py
  • Ruff and ty checks for the changed files

refactor(code): trim ACP session persistence diff

Type the ACP agent factory against the adapter's context and Pregel return,
collapse the nested error handling now that agent construction is lazy, and
drop the unrelated `mcp_tools` forwarding.
