0.21.1 — CLI Live Changelog · Kandown changelog

Added: CLI Live Changelog Display — the CLI automatically parses and displays formatted release changelogs from CHANGELOG.md directly in the terminal during auto-updates, kandown update, and version notice popups.
Added: Release Guidelines in AGENTS.md — mandatory rule requiring every release to include a comprehensive, detailed English changelog in CHANGELOG.md and attached to the release commit body.
Changed: Included CHANGELOG.md in published npm package files array so terminal displays have access to release notes in production installs.
