Tycho v0.7.4

Tycho v0.7.4

Changes

• Fix custom Claude-compatible harness execution by launching harness binaries directly instead of routing them through a Ruby runner.
• Move leading env KEY=value assignments from custom harness commands into the child process environment before execution.
• Prevent native wrappers such as mairu from being interpreted as Ruby source files during managed-agent runs.

Compatibility

• Existing custom_harnesses entries that start with env KEY=value ... continue to work.
• Managed-agent exit status is still recorded for Remote UI/TUI polling.

Validation

• bin/test passed on Ruby 3.4.7.
