The resume_session and load_session handlers were implemented but undiscoverable by ACP clients because the capabilities weren't declared in the initialize response. Adds load_session=True and resume=SessionResumeCapabilities() plus wire-format tests. Fixes#6633. Contributed by @luyao618.
Send AvailableCommandsUpdate on session create/load/resume/fork so ACP
clients (Zed, etc.) can discover /help, /model, /tools, /compact, etc.
Also rewrites /compact to use agent._compress_context() properly with
token estimation and session DB isolation.

The PR changed prev_tools from list[str] to list[dict] with name/result
keys. The gateway's _step_callback_sync passed this directly to hooks
as 'tool_names', breaking user-authored hooks that call
', '.join(tool_names).
Now:
- 'tool_names' always contains strings (backward-compatible)
- 'tools' carries the enriched dicts for hooks that want results
Also adds summary logging to register_mcp_servers() and comprehensive
tests for all three PR changes:
- sanitize_mcp_name_component edge cases
- register_mcp_servers public API
- _register_session_mcp_servers ACP integration
- step_callback result forwarding
- gateway normalization backward compat
Adds /help, /model, /tools, /context, /reset, /compact, /version
to the ACP adapter (VS Code, Zed, JetBrains). Commands are handled
directly in the server without instantiating the TUI — each command
queries agent/session state and returns plain text.
Unrecognized /commands fall through to the LLM as normal messages.
/model uses detect_provider_for_model() for auto-detection when
switching models, matching the CLI and gateway behavior.
Fixes#1402
Restore the ACP editor-integration implementation that was present on the
original PR branch but did not actually land in main.
Includes:
- acp_adapter/ server, session manager, event bridge, auth, permissions,
and tool helpers
- hermes acp subcommand and hermes-acp entry point
- hermes-acp curated toolset
- ACP registry manifest, setup guide, and ACP test suite
- jupyter-live-kernel data science skill from the original branch
Also updates the revived ACP code for current main by:
- resolving runtime providers through the modern shared provider router
- binding ACP sessions to per-session cwd task overrides
- tracking duplicate same-name tool calls with FIFO IDs
- restoring terminal approval callbacks after prompts
- normalizing supporting docs/skill metadata
Validated with tests/acp and the full pytest suite (-n0).
