add compatibility to obsidian-tasks

[championswimmer]

when using obsidian-tasks then tasks can have much more richer data

example

[x] install and setup Alfred #task #productivity #setup 🔼 ➕ 2024-12-17 📅 2024-12-23 ✅ 2025-01-08

Here,

• ➕ 2024-12-17 is when task was added
• 📅 2024-12-23 is when task is due
• ✅ 2025-01-08 is when task was completed
• 🔼 is priority

---

It would be a good idea to have searchType to expand to the following

• task.completed - to track tasks completed on given date
• task.added - to track tasks added on given date
