fix: deduplicate inspector panels (Relations, Backlinks, Referenced By) (#82)

* fix: deduplicate inspector panels by excluding frontmatter from outgoing links

The extract_outgoing_links function was scanning the entire file content
including YAML frontmatter, causing wikilinks in frontmatter fields
(e.g. belongsTo, relatedTo) to appear in both the relationships map AND
outgoingLinks. This made the same note show up in both "Referenced By"
and "Backlinks" panels.

Backend: pass gray_matter's parsed body (no frontmatter) to
extract_outgoing_links instead of raw file content.

Frontend: filter useBacklinks to exclude entries already shown in
Referenced By, ensuring strictly non-overlapping panels.
