Lance	2f483633ed	feat(claw402): preflight USDC balance before AI calls (#1479) ... * chore: ignore nofx-server build artifact Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat(claw402): preflight USDC balance before AI calls Short-circuit claw402 Call/CallWithRequestFull when the wallet balance can't cover the estimated cost of the call, surfacing ErrInsufficientFunds instead of letting x402 fail mid-flight after the sign step. - wallet: cached balance lookup (30s TTL, per-address mutex) to avoid hammering the Base RPC; separate error-returning and display-only APIs so callers can distinguish zero balance from an unreachable RPC. - claw402: 1.5× safety multiplier on the flat per-call estimate, 4.0× for reasoner models whose chain-of-thought cost can blow past the flat rate. Fail-open on RPC errors — x402 still gates actually-empty wallets, and we prefer availability over extra strictness. - shortAddr redacts the wallet in error strings to avoid leaking the full address into telemetry bundles.
