docs: Sprint 13 — F9-lite (Ollama Cloud free-text plan synthesis) across all 6 running docs

Sprint 13 (commit bae9403) splits the Sprint 11 "Generate Meal
Plan" CTA into a 2-step modal: "Use the recipe library" (default,
Sprint 11 unchanged) or "Ask the LLM" (new). The LLM path POSTs
to /api/llm/plan; the backend calls kimi-k2.6:cloud on ollama.com,
parses the LLM’s JSON picks, creates a fresh plan, fills the
LLM’s picks, and falls through to the Sprint 6+ fillEmptySlots
pattern for the slots the LLM didn’t cover. No pre-existing WIP
files touched.

This commit updates the 6 running docs that track the sprint:

- .agent/plan.md — Sprint 13 section (S13.1-S13.4) added.
- .agent/context.md — Sprint 13 (D1-D9, Q1-Q3) added; file:line
  references; key takeaways.
- Review/sprint13-verification.md — new file: 3-step browser
  smoke + 4 API curls + a11y check + 6-risk table + future
  work section.
- Review/ui-nielsen-audit.md — Sprint 13 status block (T7.1-T7.3)
  at the top, after the Sprint 12 block.
- fix-ui-audit.md — Sprint 13 section (T7.1-T7.5) added after
  the Sprint 12 section.
- Review/handoff-ui-audit.md — Batch I added to the deploy
  instructions; Sprint 13 section added after Sprint 12; TL;DR
  table row 13 added; Last-updated footer updated.
- docs/HANDOFF.md — Sprint 13 section added after the Sprint 12
  section, with a path-forward paragraph for F9-full.

All 6 docs now reflect Sprint 13. §Future backlog remaining:
F9-full (local Ollama model pull on the host) — opt-in based on
cloud-billing feedback. _ask_llm is the single seam: F9-full only
needs to swap the URL + model name.

+
+**Root cause (one-liner):** the Sprint 11 "Generate Meal Plan" CTA was library-only. Sprint 13 splits it into a 2-step modal: "Use the recipe library" (Sprint 11 unchanged) or "Ask the LLM" (new). The LLM path lets the user describe what they want for the week ("Italian-inspired, vegetarian") and uses kimi-k2.6:cloud on ollama.com to pick meals from the local library.
+
+**Scope (5 boxes):** NEW `backend/app/api/llm_plan.py` (~280 lines, 1 endpoint + 4 helpers + tolerance for malformed LLM responses), 2 schema additions (`LLMPlanRequest` + `LLMPlanResponse`), 1 router registration, 1 `mealPlannerApi.llm.plan` method, prompt modal in `Dashboard.tsx` (radio + textarea + click-outside-to-dismiss). **No new dependencies. No migration. No pre-existing WIP files touched.** Reuses `OLLAMA_BASE_URL` / `OLLAMA_API_KEY` / `OLLAMA_MODEL` from `config.py:36-38`.
+
+**LLM tolerance:** a 60s timeout, parse-failure (markdown code fences, trailing commentary), or empty response all return 0 picks; the library fill takes over. The user sees a success toast with `picked_count: 0` — same as if the LLM had returned 0 picks — never a crash.

 Trust the build output. Trust the smoke checklist. Don't trust the deployment host's UI until the user confirms. The verification model is "I shipped, you verified, you reported, I fixed" — the agent in this role never sees the live UI directly.
