coordinator

Rust coordinator service for the symbolic execution stack.

Current slice:

• exposes the public HTTP API from repos/spec/coordinator
• verifies real EIP-712 signatures for reader registration and disclosure
• tracks nonce replay protection and disclosure request state in memory
• proxies reader registration and to-reader operations to mpc
• proxies handle resolution to the coprocessor
• resolves disclosure controllers on-chain with eth_call against request.contract

Not implemented yet:

• durable storage for readers, nonces, and disclosures
• production coprocessor integration contract validation
• background polling or retry workers
