Patrick Buckley 2b58c127b1 Add pluggable storage backend (SQLite + PostgreSQL) and deployment packaging (#20)
* Add pluggable storage backend (SQLite + PostgreSQL) and deployment packaging

Database abstraction: StorageBackend protocol with 21 methods, SQLAlchemy Core
schema, SQLite backend (FTS5), PostgreSQL backend (tsvector/ILIKE), Alembic
migrations, singleton registry. memory.py reduced to thin facade. Session.py
open_db() calls replaced with generic KV methods. [database] config section
with env var support.

Deployment: Docker Compose production profile with PostgreSQL, Dockerfile with
postgres extras and migration entrypoint, Helm chart with bitnami subcharts,
Terraform AWS ECS/Fargate module with RDS + ElastiCache + ALB.

39 new storage tests (934 total). mypy strict clean. Docs and diagrams updated.

* Address PR #20 review feedback (16 items)

- Backends only call create_all() when Alembic migrations are disabled
- Helm configmap uses correct TURNSTONE_DB_BACKEND env var; DB URL
  constructed via env expansion with secret reference instead of ConfigMap
- Migration errors fail fast for PostgreSQL (only non-fatal for SQLite)
- save_memory/delete_memory wrapped in exception handling like other facade fns
- pool_size passed through from config/env to init_storage() in cli + server
- Terraform: DB URL moved to Secrets Manager, auth enabled flag set,
  optional TLS listeners with certificate_arn, Redis transit encryption on
- Docker entrypoint no longer suppresses migration output
- Diagram fixes: removed StaticPool claim, removed non-existent migration ref
- compose.yaml/README: clarified production profile requires DB env vars
