The audit-open case in gsd-tools.cjs called bare output() on both the --json
and text paths. output is never in scope at the call site — the entire core
module is imported as `const core`, so every other command uses core.output().
Two-part fix:
- Replace output(...) with core.output(...) on both branches
- Pass result (the raw object) on the --json path, not JSON.stringify(result)
— core.output always calls JSON.stringify internally, so pre-serialising
caused double-encoding and agents received a string instead of an object
Adds three CLI-level regression tests to milestone-audit.test.cjs that invoke
audit-open through runGsdTools (the same path the agent uses), so a recurrence
at the dispatch layer is caught even if lib-level tests continue to pass.
Closes#2236
