v0.1.3

Changed

• Made SMTP username and password optional in the config UI, options UI, and YAML configuration.
• SMTP authentication now runs only when both username and password are provided.
• Blank or incomplete SMTP credentials are removed from saved config data.
• Updated HACS metadata with a minimum Home Assistant version of 2024.4.1.
• Updated GitHub Actions validation to run both HACS validation and Hassfest.
• Updated manifest documentation and issue tracker links for the Wheemer fork.

Fixed

• Fixed service unload to remove email_notifier.send instead of the old send_email name.
• Avoid duplicate service registration during setup.
• Removed the SMTP connection probe from entity setup so Home Assistant startup is not blocked by a temporarily unavailable SMTP server.
• Cleaned up mutable default arguments and local attachment path handling in the SMTP API.

Documentation

• Updated README installation links, badges, fork attribution, and optional SMTP credential behavior.
