d0e09a523d feat: evaluate Qwen3.5:35B as local model option (#288)
Some checks failed
Forge CI / smoke-and-build (pull_request) Failing after 1m11s
Part of Epic #281. Verdict: APPROVED 8.8/10 security.
MoE 35B/3B active, 128K ctx, Apache 2.0, perfect data locality.

Follow-up issues filed:
- #502: live tool dispatch benchmark
- #503: reasoning benchmark vs hermes4:14b
- #518: document minimum hardware requirements fleet-wide
- #324: prompt injection red-team testing (existing)

Closes #288
