[ENH] Context for backlinks

[fgrelard]

Is your feature request related to a problem? Please describe. The sidebar shows backlinks associated to a selected node. When hovering over a backlink, a snippet of the corresponding file appears, starting at the beginning of the file.

Describe the solution you'd like The behaviour should be similar to org-roam-buffer, i.e. the snippet should show the context in which the currently selected node appears inside the backlink file.

Good suggestion! I've been meaning to add that, as well as display the actual node contents rather than the contents of the entire file, I'll start working on it.
