v0.3.68

Changed

• 📁 Per-version changelogs: Migrated from a single root CHANGELOG.md to a changelog/ directory with one file per version (changelog/vX.Y.Z.md). Every version from v0.1.1 to v0.3.67 now has its own changelog file, extracted from GitHub Release notes and git commit history. The root CHANGELOG.md has been deleted.
• src/changelog-loader.js: Refactored to scan the changelog/ directory for v*.md files instead of reading a single CHANGELOG.md. The TUI changelog display continues to work identically.
• .github/workflows/release.yml: The "Extract changelog" step now reads changelog/vX.Y.Z.md directly instead of parsing a monolithic file for a version section. Simpler and more reliable.
• package.json: Replaced CHANGELOG.md with changelog/ in the files array so per-version changelogs are included in the npm package.
• AGENTS.md: Updated changelog instructions and the /bump workflow to create per-version files in changelog/ instead of rewriting a single root file. Added a mandatory rule that the changelog content must always be used as the GitHub Release body.
• docs/development.md: Updated the release step to reference the new changelog path.
