Subject: [PATCH] feat: custom tooltip action replacing native title attributes

Add a reusable `use:tooltip` Svelte action as a drop-in replacement for
native title attributes. Styled to match the retro parchment theme with
JetBrains Mono font, dark background, and 400ms hover delay.

Replace all title attributes in NoteEditor, NoteCard, and NotesView
with the custom tooltip. The action supports top/bottom positioning
and auto-clamps to viewport edges.
