chore: scaffold PYRE MVP monorepo (structure + docs)

pnpm + TypeScript workspace per design doc §13:
- apps/{web,api,worker} skeletons (Next.js 16, Fastify 5, BullMQ)
- packages/{core,solana,prometheus,db,config} (core has real types/DTOs;
  solana/prometheus are stubs)
- programs/pyre-core placeholder (future Anchor, v1.0)
- docs/: PYRE_MVP_DESIGN (canonical), ARCHITECTURE, SECURITY, TOKEN_CLASSIFICATION
- CLAUDE.md, README, .env.example (no private-key var by design)

Skeleton + docs only — no Solana/business logic yet. All workspaces typecheck clean.

+// PYRE background worker — SKELETON ONLY.
+//
+// Minimal bootstrap stub. No queues or processors are wired up yet, and no real
+// job logic is implemented. AI services are API-based only (§11) — never run
+// local LLMs or image models on the server.
+
+// TODO: construct the Redis connection (ioredis) from @pyre/config and create a
+// BullMQ Worker per queue below, each delegating to a typed processor.
+//
+// Job types to implement (§13):
+//   - metadata-lookup        : async token metadata enrichment for scanned accounts
+//   - prometheus-generate    : AI Spawn generation via @pyre/prometheus
+//   - safety-check           : moderation + forbidden-term + ticker/name collision checks
+//   - tx-confirmation-watch  : background tracking of on-chain tx confirmation
+//   - receipt-enrichment     : enrich stored cleanup receipts post-confirmation
+//
+// AI safety (§16): filter generated names/tickers/lore; block hate, explicit,
+// extremist, copyrighted, impersonation, and scam-like outputs; require human
+// approval before any launch.
