Purge legacy pre-pivot scaffold (decided: extractor/merger-only architecture)

Browse Source 
Delete src/extract/ (pi-session normalize/extract/merge stubs), src/ledger.ts,
src/schema.ts, src/derive.ts, src/queries/, src/cli.ts (npm run ingest/graph/
what-next), data/legacy-graph/, data/agent/ (pi agentDir vestige), and their
config.ts/package.json references.

The retroactive-bootstrap goal is dropped: the live chat store (AI SDK
UIMessages) is the only session format now, and the old pi JSONLs in
data/sessions/ stay on disk, inert. contracts.ts is the single schema.

**The live graph.** Every completed turn folds the chat into append-only JSONL ledgers (`emitChat`: tree nodes/edges, quiz outcome events, taught events — idempotent, checkpointed, so partial sessions still deposit value). The home view derives node states from the ledgers and lays them out with forceAtlas2 (run-then-freeze — no idle simulation). At session start the derived graph is rendered into a compact markdown block appended to the teacher's instructions (`buildGraphContext`) — whole graph while small, hotspots + 1-hop neighborhood past 150 nodes.
## Legacy scaffold (dormant)
The pre-pivot v0 pipeline — `src/ledger.ts`, `src/cli.ts` (`npm run ingest` / `graph`), `src/extract/` (normalize ✅, extract/merge stubs), `src/schema.ts`, `src/derive.ts`, `src/queries/` — is kept compiling as reference for a future **retroactive bootstrap** over the old pi session JSONLs (`data/sessions/`, bootstrap input only). It writes to `data/legacy-graph/` and shares nothing with the live store (`data/graph/`, owned by `src/store/graph.ts` per the `contracts.ts` shapes). See `docs/architecture.md` for its design.
## Testing
All deterministic, no LLM (models are injected as `MockLanguageModelV4` where an agent loop is under test):
