feat: implement amp AI tool support and replace Taskfile with Magev0.10.0

- Add amp as default AI tool for release notes and showcase generation
- Fallback chain: amp → hexai → claude → aichat
- Replace Taskfile.yaml with magefile.go for build automation
- Update all documentation (README.md, AGENTS.md, doc/development.md)
- Update version to 0.10.0
