fix(honcho): add list mode to honcho_conclude so delete can resolve a real conclusion id

[vizi0uz]

What does this PR do?

Adds a list mode to the honcho_conclude tool so the model can retrieve a real conclusion id
before deleting one. Previously honcho_conclude's delete action was unreachable in practice: the
model had no tool that ever surfaced a conclusion's server-generated id — honcho_search only
searches the separate Message resource space, and Honcho's own conclusion-list/search endpoints
(ConclusionScope.list() / .query() in the SDK) were never wired into any tool.

This lands as a bug fix (top contribution priority per CONTRIBUTING.md) and adds no new tool — it
extends the existing honcho_conclude tool with a third mode, alongside create and delete.

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)

Changes Made

• plugins/memory/honcho/session.py:
  • Extracted the observer/observed conclusion-scope resolution (previously duplicated in
    create_conclusion and delete_conclusion) into a shared _conclusions_scope() helper.
  • Added list_conclusions(session_key, query=None, peer="user", limit=20), which calls the
    SDK's ConclusionScope.query() (semantic search) when query is given, or .list() (recent
    conclusions) otherwise, and maps results to {"id": ..., "content": ...}.
• plugins/memory/honcho/__init__.py:
  • CONCLUDE_SCHEMA: added optional list (boolean) and query (string) parameters; updated
    the tool description to document the intended list → copy id → delete flow and to clarify
    that conclusion ids are opaque, server-generated strings no other tool can surface.
  • Handler: relaxed the "exactly one of conclusion/delete_id" check to a three-way exactly-one-of
    (conclusion / delete_id / list), and added dispatch to list_conclusions().
• tests/honcho_plugin/test_session.py: added manager-level tests for list_conclusions
  (query path, list path, exception handling, no-cached-session), provider-level tests for the
  new list dispatch path, a rejection test for list combined with conclusion, and extended
  the schema smoke test to cover the new params. Updated the existing exactly-one-of error-message
  assertions to match the new three-way wording.

How to Test

1. uv run --extra dev --extra messaging python -m pytest tests/honcho_plugin/test_session.py -q
   — all tests pass (125 total, including the new ones).
2. python scripts/check-windows-footguns.py plugins/memory/honcho/__init__.py plugins/memory/honcho/session.py tests/honcho_plugin/test_session.py
   — clean.
3. Manual/live (against a self-hosted Honcho instance): honcho_conclude(conclusion="...") to
   create → honcho_conclude(list=true) to confirm a real id comes back → honcho_conclude(delete_id=<id>)
   to confirm deletion succeeds → honcho_conclude(list=true) again to confirm it's gone.

Thanks for tracing the inaccessible deletion-ID path. The current-main premise is confirmed: plugins/memory/honcho/__init__.py:1388-1406 accepts a supplied delete_id but exposes no conclusion-listing path, while plugins/memory/honcho/session.py:1190-1225 only creates or deletes.

Problems

• This changes the public tool contract, but the documentation remains stale. plugins/memory/honcho/README.md:112, website/docs/user-guide/features/honcho.md:229, and optional-skills/autonomous-ai-agents/honcho/SKILL.md:269 still describe only create/delete and say exactly one of two arguments is required.

Suggested changes

• Document list: true, optional semantic query, and the list → returned ID → delete workflow in those Honcho-facing docs (plus their generated/localized mirrors as required).
• The implementation itself matches the pinned SDK: honcho-ai==2.0.1 defines ConclusionScope.list(size=...) and query(..., top_k=...) in honcho/conclusions.py:166-251.

Automated hermes-sweeper review.

Merged via #62290 (commit 8d1c96f) — your honcho_conclude list-mode commit landed on main with authorship preserved via rebase-merge. Closes the delete_id gap from #59794. Thanks @vizi0uz!
