Note

Low Risk
Documentation-only changes; no runtime behavior or security-sensitive logic is modified.

Overview
Adds external developer/operator documentation for starknet_transaction_prover, including quickstart Docker usage, JSON-RPC method examples (notably starknet_proveTransaction), input constraints, error codes, and deployment/configuration options (TLS, CORS, concurrency, logging, CPU-specific builds).

Introduces resources/example-config.json to provide a ready-to-copy sample JSON configuration for RPC URL, networking, concurrency limits, CORS, and zero-fee field validation.
