L402 Lightning paywall + Depth-of-Identity score gate for MCP. Three tools — `l402_gate_challenge`, `l402_gate_verify`, `l402_gate_score` — let agents pay per-call without accounts: solve a PoW challenge for the free tier, or pay a Lightning invoice (L402) for the paid tier. The bundled `l402_gate_score` tool looks up the Depth-of-Identity composite for any Nostr pubkey from the public PowForge oracle, so server operators can compose price + identity gating with one call. Stdlib only — no MCP SD
