grounded Q&A with verified citations, Anthropic SDK / OpenAI-compatible /
test-only fake, daily budget, 404 when disabled), @fastify/compress (br q4),
AA-compliant shiki themes, scripts/qa/{screens,axe}.py, security regression

Phase 0–2 of docs/SPBGIT-2-PLAN.md. Fixes the production memory-restart loop
(unbuffered /raw, metadata-only blob probes, 12-way git semaphore), the stale
all-time commit total (overview cache validated against live refs), the
600 MB request log (completion-only logging), and the 24 px horizontal
overflow on every phone page. Adds /about/metrics, /api/v1/search,
/api/v1/repos/:name/tree, split diffs, lazy file tree, clone sheet.
