Uses MeshLLM built-in `mesh` collective intelligence / Mixture of Agents
when Buzz Auto sees two or more distinct physical models. With zero or
one model, Auto remains ordinary `auto`. This is an alternative way to
improve tool responses, accuracy, and resistance to hallucination when a
high-latency distributed mesh contains diverse models.
Models and members may come and go: collective routing enables only
after stable capacity, drops on confirmed contraction, and can recover
later. Mesh-specific failures retry once through ordinary Auto.
This update also pins MeshLLM to a v0.73.1-compatible backport of
[MeshLLM #1074](https://github.com/Mesh-LLM/mesh-llm/pull/1074), so
client-only Buzz nodes cannot enter model election or download a remote
provider model. Buzz preserves the selected local sharing model and
switches an existing client to sharing across a controlled app restart,
retaining one runtime and one `:9337` / `:3131` pair per machine.
Validation:
- Full local `just ci` passes on the cleaned branch.
- MeshLLM host-runtime suite: 1,568 passed, 0 failed; strict Clippy
passes.
- Buzz desktop Tauri suite with `mesh-llm`: 1,721 passed, 0 failed;
strict feature Clippy passes.
- Playwright covers client-to-share using the saved local model and no
destructive stop.
- Packaged two-machine testing proved single-model routing, dual-model
collective routing, tool-markup fallback, and runtime reuse.
- Packaged client-only recheck routed a real Mini Buzz turn through M5
while Mini stayed `is_client=true`, `is_host=false`, hosted no models,
and created no Gemma cache.
Builds on the recovery work merged in #2823; this PR does not duplicate
it.
