v1.2.4

Major Changes

• Replaced go-ethereum core/types with a self-contained txtypes package (own transaction/receipt types, RLP codec, signer, JSON marshalling and a runtime tx type registry)
• Added EIP-8141 frame transaction support with the new frametx and frametx-fuzz scenarios (all envelope shapes incl. POST_TX, keyed nonces, contract senders/paymasters, coverage-driven fuzzing, chain support detection)
• Added exclusive client groups: group(-name) removes a client from a group so reserved clients are only reachable via their group
• Fixed several concurrency and nonce tracking bugs (atomic spammer start, compare-and-swap nonce advancement, skipped nonce reuse, ClientPool selection safety, funding underflow, batcher deploy state, blocking batch errors)
• Sized erc20_bloater batches for Amsterdam state-creation gas and improved tx-fuzz throughput with stuck tx replacement
• Bumped minimum Go version to 1.26 and updated the Authenticatoor client for shared session management and background token refresh
