Pulse Verity 1.3.3

Keyless guidance: requests outside the BTC, ETH and SOL sample return NO_KEY, and a spent daily sample returns KEY_REQUIRED with the package-built developer sign-up link, the hosted server and a validated reset time, instead of a refused-key message. A configured key keeps its existing errors. Adds the hosted server to the registry listing, MCP instructions only when no key is configured, and a pulse-verity User-Agent. No price calculations change. Includes npm, desktop and Gemini packages; existing installs must update to 1.3.3.
