Cache scrollTop alongside blocks in the tab swap cache. On tab leave,
capture the scroll container position; on tab restore, apply it via
requestAnimationFrame after blocks are rendered.

When the editor's first block is an H1 heading, the note title
automatically stays in sync. Changes are debounced at 500ms.
Manual rename via tab breaks the sync until the tab is switched.
- Show H1 in editor (stop stripping on load, stop reconstructing on save)
- New useHeadingTitleSync hook tracks sync state and debounces title updates
- handleEditorChange keeps frontmatter title: in sync with H1
- Fast path for H1-only content preserves instant new-note interactivity

Extract heading-stripping logic into `extractEditorBody` — fixes a bug
where the regex failed to strip the title heading from newly created
notes (because `splitFrontmatter` left a leading newline that the
regex didn't account for).
Add a fast path in `doSwap` for empty body content: when the body is
empty (common case for new notes), skip the potentially-async
`tryParseMarkdownToBlocks` pipeline entirely and apply a single empty
paragraph block synchronously. This eliminates the multi-second delay
caused by BlockNote's async markdown parser initialization.
