Release v1.10.1

Documentation

• Added llms.txt (AI-agent entry point following the llmstxt.org standard) and doc/recipes.md (8 copy-paste recipes for common scenarios) — both ship with the package so consumer-side AI tooling can discover the API
• Expanded CONTRIBUTING.md with development setup, test-suite instructions, and a PR checklist
• Added CLAUDE.md / AGENTS.md (symlink) covering common commands, layout, and gotchas for contributors

CI / tooling

• Added GitHub Actions workflow that runs dart format check, dart analyze --fatal-infos, flutter test, and flutter pub publish --dry-run on every push and PR to master/develop
• Added 47 widget and unit tests covering every public widget plus MessageGroupHelper and Algo.dateChipText
• Added scripts/release.sh to codify the publish flow into a single command
• Reformatted lib/ to match dart format defaults
