fix: brainstorm infinite loop, ghost cursor, embedding ::vector cast, semantic search, billing stats, usage meter accordion

- Fix useBrainstormSocket: stable guestId via useRef, remove setState in cleanup - Fix GhostCursor: direct DOM manipulation via refs, no useState re-renders - Fix all SQL embedding queries: add ::vector cast on text columns - Fix embedding truncation to 15000 chars (under 8192 token limit) - Fix NoteEmbedding INSERT: remove non-existent updatedAt column - Fix billing page: show all quota stats in grid instead of single metric - Fix usage meter: accordion expand/collapse, per-feature detail - Fix semantic search: rebuild 103 note embeddings, ::vector cast on vectorSearch - Fix brainstorm expand/manual-idea/create: ::vector cast on embedding SQL

- Style architectural / papier, 2–4 formes géométriques ou lignes, palette sobre (noir/gris/une couleur douce), pas de texte lisible

-Titre: ${plainTitle || '(sans titre)'}
-Extrait: ${plainBody.slice(0, 400)}`
+OUTPUT: Only raw SVG markup. No markdown, no code fences, no comments. Start with <svg and end with </svg>.
+
+SPECIFICATIONS:
+- viewBox="0 0 224 168", NO fixed width/height attributes
+- Maximum 1000 bytes
+- Background: soft warm beige (#F5F0E8) or transparent
+- Color palette (pick 2-3): warm charcoal (#2C2C2C), slate gray (#6B7280), soft sage (#A8B5A0), muted ochre (#C4A882), dusty rose (#C9A9A6), teal (#5F9EA0), burgundy (#8B4513)
+- NO text, NO scripts, NO foreignObject, NO external links
+
+CRITICAL: The illustration MUST be recognizably related to the topic.
+Think of it like an ICON or PICTOGRAM for the title. Not abstract random shapes.
+
+TOPIC: "${plainTitle || 'untitled'}"
+
+How to illustrate this topic (pick the BEST match):
+- If the topic is about CODE/DEV: Show angle brackets <>, curly braces {}, a terminal window shape, or circuit-like lines
+- If the topic is about MUSIC: Show sound waves, musical notes shapes, or speaker icon
+- If the topic is about FOOD/COOKING: Show a pot shape, utensils, or plate
+- If the topic is about TRAVEL: Show a path/road, mountain peaks, or compass
+- If the topic is about SCIENCE: Show atom orbits, flask/beaker, or molecule bonds
+- If the topic is about BUSINESS/FINANCE: Show ascending chart lines, coins, or briefcase
+- If the topic is about HEALTH: Show heart shape, pulse line, or leaf
+- If the topic is about EDUCATION: Show book shape, graduation cap, or pencil
+- If the topic is about NATURE: Show tree, mountain, water wave, or sun
+- If the topic is about DESIGN/ART: Show palette, brush stroke, or frame
+- If the topic is about PEOPLE/TEAM: Show overlapping circles, handshake, or connected nodes
+- If the topic is about ARCHITECTURE: Show building outline, blueprint grid, or columns
+- Otherwise: Extract the KEY CONCEPT from the title and draw its SIMPLEST iconic representation
+
+TECHNICAL RULES:
+- Use simple shapes: <circle>, <rect>, <line>, <path>, <ellipse>, <polygon>, <g>
+- Keep it FLAT and MINIMAL — 2-4 elements max
+- Use opacity for depth (0.3-0.8)
+- The icon should be immediately recognizable even at small size
