Show HN: A local merge queue for parallel Claude Code agents

A local, zero-cost merge queue for parallel Claude Code agents is introduced, designed to serialize agent operations to prevent push races, redundant heavy builds, and shared-resource test flakiness. The system supports configuration options such as branchPrefix, worktreeSuffix, portBase, integrationBranch, and productionBranch. It also allows defining protectedBranches, regenerableFiles, symlinks, buildOutputDirs, and a checkCommand for gating landings, with checksRequired to enable or disable these checks. The project is open-source under the MIT license.
