Feat: Adds logic to look for links in frontmatter

[putzwasser]

Parses the frontmatter data for wiki links

• Adds outgoing/backlinks to the graph
• Adds backlinks to the backlink pane

imo this shouldn't be allowed (even obsidian doesn't show these links in the graph if they aren't in the links field iirc?)

we should expose the ability to parse a wikilink as a function so that plugin authors may opt-in to that behaviour if they would like though

Actually, it does. In the links pane, in the backlinks section and in the graph :) This motivated me to create this (code-wise rather clumsy) PR.

So, this change would be completely compatible with "raw" obsidian without plugins.

Additionally, this allows to create an obsidian breadcrumbs plugin for quartz.

cc @saberzero1, since you are looking into markdown parser, might be of interests, but lower triage than the refactor.
