Change poe changelog to bullet points with project and change type
Updated changelog format to use bullet points with:
- Project name in bold at the start
- One or two sentence description
- Change type in italics at the end (new feature, bug fix, enhancement, etc.)
Example output:
- **ocaml-zulip**: Fixed encoding bug in channel lookups. *bug fix*
- **poe**: Updated to use Opus 4.5 model. *enhancement*
