Smooth-scroll for the anchor jump when the target note is already
stacked, instant otherwise. While threading the new flag, the four
positional params got hard to read, so collapse them into
{ noteId, notes, hash, smoothHash } and update all call sites.

Links like `path/to/note.md#heading` previously errored with "Note not
found" because the full href (including `#hash`) was matched against
file paths. Split the fragment off in the link handler, plumb it through
the event bus, and scroll the matching heading into view once the
target note is in place. Headings now get GitHub-style ids via
markdown-it-anchor + github-slugger so the anchors actually exist.

- Pass didrkey (with colons) instead of classNameId to scrollToFocusedNote in StackedPublicNote, so findIndex matches the URL-stored ID
- Revert includes() to strict === in findIndex for semantic correctness
