chore(test): synchronized test expectations with output and cleanup formatting

- Updated `hashline` test expectations to match new recovery message strings.
- Initialized settings in `interactive-mode-status` tests to prevent state leakage.
- Added ANSI color code verification to `launch` tool tests to align with updated output.
- Cleaned up whitespace in `tan-context-switch.md` system prompt.
