Move semantic_search_notes off the full-table Python cosine scan onto a native
pgvector column: indexed ORDER BY embedding <=> :q LIMIT k (HNSW, cosine).
Migration 0067 enables the extension, converts the JSONB embedding column to
vector(384) (stale-dim rows dropped and regenerated by the startup backfill),
and builds the HNSW cosine index. Postgres image moves postgres:16-alpine ->
pgvector/pgvector:pg17 across prod, quickstart, and CI.

Renames src/fabledassistant -> src/scribe and all imports, plus the
default DB name and DB user/password (fabled -> scribe) in config +
compose. 952 refs / 154 files. Reverses the old 'internal name stays
fabledassistant' convention.
Code-only: live databases are still physically named 'fabledassistant'.
Deployed environments must set POSTGRES_DB / POSTGRES_USER (or rename the
DB) since the defaults now resolve to 'scribe'. Repo (FabledScribe), git
host (fabledsword), MCP (fabled-git) and the image name (fabledscribe)
are intentionally unchanged.
ruff check src/ clean locally; CI (typecheck + pytest) is the gate.

Mitigation for the nightly fabledscribe Postgres outage on the
vdnt-docker02 Swarm node (incidents 2026-05-15/16/17 around 03:50 UTC).
Confirmed kill chain (not the trigger): a brief host-level setns/exec
stall makes the Docker healthcheck exec fail with exit 1 → unhealthy →
SIGKILL → fast-shutdown can't finish on NFS in 10s → exit 137 → swarm
restart_policy.max_attempts: 5 burns out → DB stays dead.
Hardens the `db` service so a transient host blip can't escalate to
killing the database:
- stop_grace_period: 120s (gives PG room to fsync on shutdown)
- healthcheck: interval 30s / timeout 10s / retries 10 / start_period 180s
(only gates app startup order — not authoritative liveness)
- prod: restart_policy condition=on-failure, max_attempts=0, window=120s
- quickstart/dev: restart: unless-stopped
Host-side trigger (what stalls runc/exec at ~03:50 UTC) is still under
investigation — see project_pg_nightly_outage.md.
Note: the Portainer prod stack differs from docker-compose.prod.yml
here (NFS bind, traefik labels, no ollama). The same `db:` block needs
to be pasted into Portainer for the prod mitigation to apply.

Updates user-visible branding across frontend (PWA manifest, page title,
Settings, push fallback), backend (email templates and subjects, LLM
system prompt, CalDAV displayname, SMTP from-name default), README,
quickstart compose, and MCP server description.
Also updates the CI image path and quickstart image reference to
git.fabledsword.com/bvandeusen/fabledscribe in preparation for the
Forgejo repo rename. Internal Python package, env vars, and database
schema unchanged.

Adds docker-compose.quickstart.yml that pulls the pre-built image from
the registry so users can get started without a local build. Updates
README Quick Start to use the new file as the default path.
