/**
* Lithium Mining Test Agent โ end-to-end PoW mining through MCP tools.
*
* Computes real proofs using the uhash binary, submits on-chain,
* validates every step, and tests error cases.
*
* Requires:
* - Funded BOSTROM_MNEMONIC in .env
* - uhash binary built at UHASH_BIN path
*
* Usage:
* node test-mining.mjs
*
* Env:
* UHASH_BIN โ path to uhash binary (default: ../universal-hash/target/release/uhash)
* MINE_TIMEOUT โ mining timeout in seconds (default: 120)
* SKIP_V4 โ set to "1" to skip v4 seed-based mining
* SKIP_LITHIUM โ set to "1" to skip lithium v1 mining
* SKIP_ERRORS โ set to "1" to skip error case tests
