Make gemma4:e2b the default chat model - #250

Conversation
llama3.2 missed 2 of 8 grounded questions on `make eval-chat` (one false refusal, one miscite). gemma4:e2b cleared all 8 across three runs at about 2.5 s to first token, the fastest of every model that cleared the set (qwen3:4b, qwen3:8b, gemma4:e4b, lfm3, muse-glimmer:30b were also run; rows are in crates/b2-llm/evals/results.jsonl). The picker's 32 GB rung goes: the only model that earned it, muse-glimmer 30B, takes 26 s to first token, too slow to recommend. Two rungs remain, gemma4:e2b and gemma4:e4b. Thinking on/off is the lever behind the gap and is tracked as #249. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…rify, undici Rust: candle 0.9 pinned zip ^7.2, which carried the critical alert (fixed in 9.0.5); candle 0.11.1 moves it to zip 9.4.1. rustls goes to 0.23.46 for its two advisories. `make eval` on both corpora prints the same rows as the last run on main, so the bump does not change the embedding space (ADR-0007). `make ci` is green. npm: vite 6.4.5, dompurify 3.4.17 and undici 7.30.2 (via jsdom), all within the ranges package.json already allows. Left open: glib 0.18 on Linux, pulled in by gtk 0.18 under Tauri 2. It cannot move until Tauri does. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
