0.73.4 — Notification polish, settings redesign, big-list performance

Notifications polish (0.72)

Action buttons in toasts now read correctly in both light and dark themes — switched to --interactive-normal / --interactive-hover (the previous hover state resolved to near-black on some light themes).
Shorter action labels. Toasts like Jump to 'Family budget' parent collapse to Jump to parent. The destination context is already in the toast body.
Reveal opens the Files panel first. Reveal used to scroll/highlight inside a collapsed Files panel — invisible, requiring a second click after manually opening Files. Now Stashpad reveals the file-explorer leaf and then calls revealInFolder, so the result is visible on first click.

Lengthened contribution-stamp debounce, and skipped entirely when an editor is active. In a multiplayer-on-network-drive scenario the client's processFrontMatter was racing with another user's open editor on the same note, occasionally eating a few of their typed characters.
Park contribution stamps when another client just wrote. A new external-modify classifier distinguishes our own vault.modify events from another client's. Within a 1.5s grace window after an external write, our own contribution stamps wait so they don't clobber the other writer.

.md drops in _imports auto-adopt. Mirrors what .stash drops already did. The file is renamed up into the Stashpad root (de-duplicating the basename with -1 / -2 on collision) and gets the standard orphan-frontmatter backfill (id, parent, created, attachments).
Optional auto-navigate after move. Two new settings, both off by default:
- autoNavOnMoveIn: after moving via the in-list move picker, drill into the destination so you follow the note.
- autoNavOnMoveOut: after outdent, the cross-parent picker, or "Move to Home" from the context menu, drill into the destination.

Tabbed settings UI. The single tall scroll is now six tabs: General / Diagnostics / Authorship / Templates / JD Index / Hotkeys.
Full-text search at the top of the settings tab. When the box is populated, the body switches to "all sections grouped by tab heading" mode and filters out non-matching items. Clearing the query reverts to the single-active-tab view.
All 39 inventory items were cross-walked and confirmed present in the new layout — nothing was lost in the move.

[[…]] autocomplete now includes all file types — images, PDFs, audio, and other attachments — not just markdown notes. Markdown notes still insert as [[Title]] (basename, no extension); other files insert with their extension. .edtz (Encrypted Templater) files are excluded.

Skip the full render on arrow-key nav and plain row clicks. Each cursor move on a 200+ note folder used to call render(), tearing down and rebuilding every row (markdown hydrate, drag handlers, authorship-footer reads, etc.) just to flip two CSS classes — measured at 100–300ms per keystroke on a cold cache.
New repaintSelectionClasses() walks the existing row DOM and updates the selection classes in place, leaving everything else untouched.
