Michael Neale 63efbb24b6 feat(buzz-agent-core): pin goose by git rev, wire session/set_model ...

Makes the spike reproducible off this machine and closes the model-switch
stub.

- Depend on aaif-goose/goose @ 305849b71 (v1.44.0, ancestor of origin/main)
  instead of a local path. Verified: cargo fetch + full test run from a clean
  git checkout of the dep.
- session/set_model now takes effect. The id is staged in `pending_model` and
  consumed by the next session/prompt, matching buzz-agent's "applies from the
  next prompt" contract (lib.rs:494-502) so an in-flight turn is never mutated.
  Rebuilds the provider and hot-swaps it via update_provider; SharedProvider is
  an Arc<Mutex<Option<..>>> for exactly this.
- New stdio test covers unknown-session, empty-modelId, and a real switch
  followed by a completing turn.

15 tests green. Measured release binary (macOS arm64):

  new  32.5 MiB raw / 9.9 MiB gzip -9
  old   9.8 MiB raw / 3.9 MiB gzip -9
  delta +22.7 MiB raw / +6.0 MiB gzip

Corroborates PR #1526's +22.9 MiB raw / +6.2 MiB gzip.
