When compact tools (read_file, write_file, str_replace, etc.) failed,
they would fall through to the non-compact output path, causing:
- Missing or incorrect headers
- Stray footers with wrong formatting
- State leakage (is_shell_compact) between tool calls
Now failed compact tools display in the same single-line format as
successful ones, just with a truncated error message instead of the
success summary:
● read_file | path/to/file.txt | ❌ Failed to read file... | 123 ◉ 0ms
This keeps the UI consistent and avoids the "stray footer" bug.
