ensure_model() can take minutes to pull a multi-GB model, which
exceeds Hypercorn's startup timeout. Now fires as an asyncio
background task so the app starts immediately.

Stop wiping Alembic version tracking on every restart. Now
`alembic upgrade head` runs only pending migrations, as intended.

The Dockerfile runs `alembic stamp --purge base && alembic upgrade head`
on every restart, so all migrations re-run against an existing database.
Migration 0004 used `op.add_column()` which fails on re-run with
"column already exists". Migration 0005 used `op.create_table()` which
would fail similarly.
Both now use raw SQL with idempotency guards:
- 0004: `DO $$ BEGIN ALTER TABLE ADD COLUMN ... EXCEPTION WHEN
duplicate_column` + `IF EXISTS` check before touching the tasks table
- 0005: `CREATE TABLE IF NOT EXISTS` + `CREATE INDEX IF NOT EXISTS`

Phase 4: Full chat system with SSE streaming, note-aware context, and
conversation persistence.
Backend:
- Migration 0005: conversations + messages tables with FKs and indexes
- Conversation/Message SQLAlchemy models with relationships
- LLM service: ensure_model (auto-pull on startup), stream_chat (NDJSON),
generate_completion, fetch_url_content (HTML stripping), build_context
(keyword extraction, related note search, URL content injection)
- Chat service: conversation CRUD, save_response_as_note,
summarize_conversation_as_note
- Chat routes blueprint: 9 endpoints including SSE streaming for messages,
save/summarize as note, Ollama model listing
- Auto-pull llama3.1 model on app startup (non-blocking)
Frontend:
- apiStreamPost: SSE client using fetch + ReadableStream
- Chat Pinia store with streaming state management
- ChatView: dedicated /chat page with conversation sidebar + message thread
- ChatPanel: slide-out panel with contextNoteId from current route
- ChatMessage: markdown-rendered message bubble with "Save as Note" action
- Updated AppHeader with Chat nav link + panel toggle button
- Updated App.vue to mount ChatPanel with route-derived context
- Added /chat and /chat/:id routes

Rewrite migrations to raw SQL with IF NOT EXISTS/EXCEPTION guards for
full idempotency. Add notes table migration (0001), fix migration chain,
and run alembic upgrade head in Dockerfile CMD on container start.
Update summary.md with Phase 3.5 changes and Alembic instructions.
