Walkthrough

Message handling in the bot now ignores non-command messages in group and supergroup chats while still sending the help prompt in private chats. The Dockerfile runtime stage installation of CA certificates was changed to add the --no-scripts flag to apk to prevent maintainer scripts from running.

Changes

Cohort / File(s)	Summary
Message handling internal/bot/bot.go	In handleMessage, added an early return to skip non-command messages for group and supergroup chat types; help prompt is now sent only for private chats.
Runtime image install Dockerfile	In the runtime stage, changed apk --no-cache add ca-certificates to apk --no-cache --no-scripts add ca-certificates to prevent maintainer scripts from running during package installation.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Small, focused changes across two files (one behavioral, one build/runtime tweak).
• Areas to check:
  • internal/bot/bot.go: ensure chat type values match runtime Telegram library enums and no side effects for bot admins in groups.
  • Dockerfile: verify no required maintainer scripts are needed for CA certificate installation in this base image.

Poem

🐰 I hop through code and tidy trails,
In groups I hush my tiny wails,
But in a private, cozy nook,
I offer help — a friendly look.
Paws on keys, I celebrate these tweaks! 🥕

23-23: Verify that --no-scripts doesn't break CA certificate installation.

The --no-scripts flag is a good security practice to prevent arbitrary code execution during package installation. However, confirm that CA certificates are properly installed and function without post-install scripts, particularly for SSL/TLS validation in the runtime environment.

Please verify:

1. That the --no-scripts flag is supported in alpine:latest
2. That CA certificates are properly installed and functional after application startup

You can test this by running the container and verifying HTTPS connections work as expected.
