Fabler x402 Tools v1.0.7

Adds fabler_market_funding_spreads to the wallet-enabled stdio and Desktop client. It calls the live funding-spreads API for a fixed $0.001 USDC payment on Base, with an optional validated symbol. The client now exposes nine tools, eight paid and one free catalog. The official remote MCP surface remains unchanged and free-only.

Fresh npx install: npx -y https://github.com/fablerlabs/x402-tools/archive/refs/heads/main.tar.gz (the github: package shorthand is avoided because npm 10.9.8 can fail in its Git fetcher before running the package).
