- Added top-level parsing and segment splitting to apply bash fixups only on safe command chunks.
- Replaced `stripTrailingHeadTail` usage with `applyBashFixups` and array-based notice formatting.
- Fixed terminal `| head`/`| tail` and redundant `2>&1` stripping while preserving command semantics.
- Updated fixup tests for cross-command cases and removed superseded head-tail-only test coverage.
