Enhance NLP for Recurring Events

It would be great to expand Akiflow's natural language processing (NLP) capabilities for setting up repeating events. Currently, some common recurrence patterns aren't recognized, such as:

• “every Sunday”

• “weekly”

• “every 7 days”

• “every other Sunday” / “every other week on Sunday”

• “every morning at 8AM”

• “on Wednesdays at 8AM”

• “every month on the 1st/15th/etc.” / “on the 1st of every month”
