Add settings page, model management, and chat UX improvements

- Settings infrastructure: key-value settings table, GET/PUT API, Pinia store
- Configurable assistant name (default "Fable") in settings and LLM system prompt
- Model catalog with 18 models in 3 categories (General Purpose, Coding,
  Uncensored / Creative Writing) with download/select/remove functionality
- Move Ollama status indicator from chat views to global nav bar
- Chat bubble layout: user messages right-aligned, assistant left-aligned
- Floating dark input bar with auto-focus and circular send button
- Fix HTML entity rendering (' apostrophe issue in marked/DOMPurify pipeline)
- Fix new chat button navigation (fetchConversation before router.push)
- Recent chats section on home page with "New Chat" button
- Update summary.md with Phase 4.5 changes

 ### How Migrations Run
@@ -419,6 +435,20 @@ When adding a new migration, follow these conventions:
 - [x] **Frontend SSE client:** `apiStreamPost()` uses fetch + ReadableStream to parse SSE data lines
 - [x] **Auto-title:** Conversation title auto-set from first user message content
 
+### Phase 4.5 — Chat UX + Settings + Model Management ✓
+- [x] **Settings infrastructure:** Key-value `settings` table, `GET/PUT /api/settings`, Pinia store with defaults
+- [x] **Configurable assistant name:** Default "Fable", editable in settings, injected into LLM system prompt and chat message labels
+- [x] **Settings page:** `/settings` route with assistant name form + model catalog
+- [x] **Model catalog:** 18 models across 3 categories (General Purpose, Coding, Uncensored / Creative Writing) with descriptions, sizes, and best-for labels
+- [x] **Model management:** Download (pull), select (set as default), and remove (delete from Ollama) with confirmation UI
+- [x] **Status indicator in nav bar:** Moved from per-component (ChatView/ChatPanel) to global AppHeader; green/yellow/red dot with label
+- [x] **Chat bubble layout:** User messages right-aligned (primary color bg), assistant messages left-aligned (card bg), speech bubble tails
+- [x] **Floating dark input bar:** `#1c1c1e` background, rounded corners, circular send button with arrow
+- [x] **Auto-focus input:** Chat input auto-focuses on mount, conversation switch, and after sending
+- [x] **HTML entity fix:** Three-layer approach — decode entities before marked, DOMPurify sanitization, explicit `'` → `'` replacement after sanitization
+- [x] **New chat navigation fix:** `fetchConversation()` called before `router.push()` so `currentConversation` is set immediately
+- [x] **Recent chats on home page:** 3 most recent conversations shown as clickable cards + "New Chat" button

-**Phase:** Phase 4 complete. LLM chat integration with streaming responses.
+**Phase:** Phase 4.5 complete. Chat UX improvements, settings page, model management.
 - Full note-taking and task-tracking CRUD with markdown, wikilinks, backlinks, tags
 - Unified note/task model (a task is a note with `status IS NOT NULL`)
 - LLM chat via Ollama with SSE streaming responses
 - Note-aware context: auto-includes current note + searches related notes by keyword
 - URL content fetching: detects URLs in messages, fetches and includes content
 - Save assistant messages as notes; summarize entire conversations as notes
-- Dedicated `/chat` page with conversation sidebar + message thread
+- Dedicated `/chat` page with bubble-style messages (user right, assistant left), floating dark input bar
 - Slide-out chat panel accessible from any page, auto-includes note/task context
-- Auto-pull default model (`llama3.1`) on startup
-- Ollama health check: status indicator on chat views (green/yellow/red dot) with 30s polling; disables send when not ready
+- Settings page: configurable assistant name (default "Fable"), model catalog with 18 models in 3 categories
+- Model management: download, select, and remove models from the settings page
+- Ollama status indicator in global nav bar (green/yellow/red dot) with 30s polling
+- Recent chats section on home page with quick "New Chat" button
+- HTML entity rendering fix (apostrophes in marked → DOMPurify pipeline)
 - Dark/light theme with CSS custom properties
