Add linting and error reporting using vfile-reporter

[UlisseMini]

Wishlist for things I could statically catch

• [ ] Report dangling [[wikilinks]] before they 404 in prod (blocked)
• [ ] Warn about long math (won't display on small screens) (not sure if this is possible without browser emulation)
• [ ] Warn about spelling/grammer mistakes (a unified plugin should exist, gotta make sure it isn't annoying tho)
• [x] Warn about using $$math$$ since obsidian handles it differently (see #13)
