Teknium 25481d4286 feat: restore ACP server implementation from PR #949 (#1254)
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).
