একটি ভাল কমিট এবং কমিট মেসেজ কি তৈরি করে?

GOOD message structure:
  Short summary line (~50 chars, imperative mood, capitalized, no period)
  <blank line>
  Optional body: explain WHAT and WHY (not how — the code shows how),
  wrap at ~72 chars. Reference issues if relevant.

✅ GOOD:
  Add user email validation to registration form

  Validate email format before submission to prevent invalid
  accounts. Fixes #142.

❌ BAD:
  "fixed stuff", "update", "asdf", "changes", "wip"
  → vague, uninformative — useless when reviewing history later
