Feature request: function to read (other) note's content

[Grazfather]

I would like to write a code block in bb that can aggregate data from other blocks.

• In its simplest form, we can just slurp a note's content by guessing its filename (a note can be in a subdir)
• better yet, a function to resolve to the file name, or to some handle on a note
• better yet, some way to get data about a note.

This could perhaps be implemented via babashka pods, where a TS pod interacts with the obsidian vault and uses the pod RPC mechanism to provide this sort of data to a babashka client.
