- Added optional `/loop` `count|duration` command arguments and wired `command.args` into loop handling.
- Implemented `loop-limit` parsing and runtime types/helpers for iteration and duration budget limits with validation.
- Updated interactive mode to enforce loop limits per iteration, check duration expiry, and clear budget state on disable.
- Added loop-limit parse/runtime tests and fixed `/loop` arg errors plus macOS `MallocStackLogging` environment leakage.
