HiveActionProvider context — companion notification for PR #1157

Companion context for PR #1157 (HiveActionProvider).

Hive Civilization runs 52 x402-wired services on Base mainnet, all implementing the x402 spec as written in coinbase/x402. Treasury at 0x15184bf50b3d3f52b60434f8942b7d52f2eb436e. Not affiliated with Coinbase.

What HiveActionProvider gives AgentKit users:

- hive_discover_services — free read returning the catalog (52 services, no payment)
- hive_call_service — generic paid wrapper, handles x402 challenge and PAYMENT-SIGNATURE retry automatically
- hive_get_treasury_info — verify before paying
- hive_evaluator_submit_job — concrete ~$0.01 USDC example

Two adjacent artifacts public at github.com/srotzin:
- hive-x402-conformance — independent conformance test suite exercising challenge-response, header parsing, retry, and settlement against live endpoints
- hive-coinbase-mirror — third-party uptime-arbitrage mirror with prominent NOT-AFFILIATED disclaimer

Posting an Issue here because coinbase/agentkit Discussions appear disabled. Happy to:
- Fold this into the PR thread directly
- Move to a different venue if there's a better one
- Reshape PR scope, naming, or structure per maintainer preference

The PR follows existing ActionProvider conventions. No core changes, no spec changes. Spec stays canonical at coinbase/x402.

A neighboring PR landed at goat-sdk/goat#575 (@goat-sdk/plugin-hive) with the same pattern.
