Pull Request Overview

This PR consolidates Git commit attribution by adding a .mailmap file to unify all commits under a single author identity with consistent formatting. This ensures that git shortlog displays all commits from Den Delimarsky under one name with the flower emoji.

• Adds .mailmap file to standardize author name formatting across all commits
• Maps all Den Delimarsky commits to use the flower emoji variant consistently

.mailmap:2

• The .mailmap entry is incomplete. It should specify which email addresses or names to map from. The current format only defines the target identity but doesn't specify what to map to it. Consider adding the source email/name patterns, for example: Den Delimarsky 🌺 <email@domain.com> <old-email@domain.com> or Den Delimarsky 🌺 <email@domain.com> Den Delimarsky.

Thank you @yarikoptic for this very important call-out 🤣 I should, indeed, always have a flower next to my name. That being said, let's not introduce this particular metadata piece in the code base for now.
