Fix review issues from Claude's code review

- Default taskSupport fallback to "forbidden" per MCP spec (was "optional")
- Fix import path to use @/ alias consistently
- Fix misleading "type guard" comment on getTaskSupport
- Extract getTaskSupport to a variable to avoid duplicate calls in render
- Export ExtendedTool and import in tests instead of duplicating
