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

-- Default flow: tries `hexai` first by piping the generated commit/diff payload to stdin and passing an instruction prompt as the sole argument (equivalent to `cat SOMETEXT.txt | hexai PROMPT`).
-- Fallback: if `hexai` is not available or fails, falls back to `claude --model sonnet`, then to `aichat`.
-- Explicit tool: `--ai-tool claude` or `--ai-tool aichat` influences the fallback preference, but `hexai` is still attempted first when available.
