feat(ux): modify wrapping behavior of compact tool output

- tool 'name' will not be truncated up to 25 chars
- tool invocation 'description' locks to first line of output (and truncates if nec)
- result 'summary' will appear on first line if space is available, otherwise can wrap to second line. (no content wrapping expected beyond second line)
