Cody: Limit completions to 2 lines in single line mode (#276)

This commit limits code completions to 2 lines when in single line mode,
to avoid cluttering the editor with too many lines.

Added unit tests for:

- Completing up to 2 lines
- Completing 1 line if the second line is indented

This fixes a UX issue where inline completions look like a truncated
multi-line completion, e.g.:
