Refactor following review:
• Dropped Postgres backend entirely. Don't ship complexity solo devs
don't need. SQLite is the one canonical default — single file at
~/.hanzo-bot/brain/brain.db, zero infra, single static binary.
• Kept the BrainStore interface pluggable. New `registerBackend(name,
factory)` API lets 3rd parties ship Postgres / LanceDB / D1 / libSQL
as sibling extensions without forking core memory. Env override
HANZO_BRAIN_BACKEND=<name> selects at runtime.
• Renamed package @hanzo/bot-memory-postgres → @hanzo/bot-memory.
Single source of truth for the BrainStore contract; SQLite is the
one backend that ships with the bot.
• README per extension:
brain/README.md — meta-pack overview + gbrain comparison
memory/README.md — schema spec + pluggability + driver
graph-links/README.md — edge-type table + zero-LLM rationale
recipes-brain/README.md — swipe-train loop + recipe authoring
• Pluggability tests added — registerBackend exposes new backends,
unknown backend throws a helpful error.
Tests: 18/18 brain extensions pass (was 16, +2 for pluggability).
End-to-end smoke confirms: SQLite default, listBackends()=["sqlite"],
edges + facts + FTS hybrid search + recipe load all green.
The Postgres path can come back as @hanzo/bot-memory-postgres in a
separate package later. Schema is fully spec'd in memory/sqlite.ts so
re-implementation is mechanical.
