Add Kiro CLI support

Kiro CLI (https://kiro.dev) is an upgrade replacement for Amazon Q Developer CLI
with full custom prompt support.

Changes:
- Added 'kiro' to AGENT_CONFIG with .kiro/ folder structure
- Updated CLI help text to include kiro option
- Added Kiro CLI to README supported agents table
- Updated release script to generate Kiro packages
- Kiro uses .kiro/prompts/ directory (markdown format)

Kiro CLI provides the same functionality as Q Developer CLI but with
proper support for custom arguments in slash commands.
