Trim sidebar to New chat/Patients/Settings; document project vision

- app-sidebar: remove the "Saved" and "Conversations" nav items (dead #
  links) and the "temetro / Clinic" team switcher; footer is now a plain
  "temetro · open source" wordmark. Keep the notifications bell. Drop the
  now-unused Bookmark/MessageSquare/Logo/TeamSwitcher imports.
- CLAUDE.md (frontend): rewrite "What this is" to match the current
  patient-records flow (/patient cards, sparklines, create/edit dialog over
  the mock fixture) and point to the project vision; note team-switcher.tsx
  is unused.

+`temetro` — an **open-source** clinical "AI middleman" (see the project vision in the root
+`../CLAUDE.md`). This app is the clinician-facing chat UI. It is **UI-only** — no backend, no real
+model call — but it now drives a working patient-records flow over a **mock fixture**
+(`lib/patients.ts`, in-memory, session-only):
+
+- The chat parses `/patient <file#>` (or a bare `/<file#>`) in `components/chat/chat-panel.tsx` and
+  renders the record as a horizontal row of cards (`components/chat/patient-cards.tsx`), with small
+  dependency-free trend sparklines (`components/chat/sparkline.tsx`). Each card opens a detail
+  dialog; the Summary card has an **Edit record** button.
+- Patients can be **created and edited** via the shared `components/chat/patient-form-dialog.tsx`
+  (mode `create` | `edit`). The "Add patient" pill in `chat-input.tsx` opens it; saving writes to the
+  fixture (`addPatient`) and opens/updates the record in the chat.
+- Non-command messages still get a mock assistant reply.
+
+The signing / patient-owned-storage / approval features described in the root vision are **not built
+yet** — the fixture is the swap point for a future API.
