setting/project system prompt support to link note template

[Emt-lin]

Is your feature request related to a problem? Please describe. Currently, it's not inconvenient for editing or viewing setting/project system prompt. So, we should add a more convenient way to edit prompt.

Describe the solution you'd like liking custom prompt syntax.（{[[Note Title]]} represents a note.）, we can also support note template syntax.

** Currently, it's inconvenient for editing or viewing**

If that is the case, I fully agree and support your feature request. 😄
