docs(memory): document the Honcho backend (#4822)
The Honcho backend landed in #4730 without user-facing docs: the main
README's Long-Term Memory section covers the other opt-in backends
(mem0, openviking) but never mentions honcho, and unlike mem0 the
backend shipped no guide README.

- Add backends/honcho/README.md mirroring the mem0 guide structure:
  configuration (with the plain-HTTP api_key guard), workspace-per-user
  isolation and fail-closed identity, recall/search behavior per mode,
  limitations (no fact CRUD -> gateway 501, no DeerMem migration), and
  async/failure-policy semantics.
- Add a short honcho paragraph + guide link to the README Long-Term
  Memory section, alongside the existing mem0 paragraph.
