nrobi144 7a18e30fc4 feat(desktop): hashtag-spam filter with collapse-with-reveal
Damus-inspired content filter that collapses notes abusing `t` hashtag
tags into a compact reveal-on-click placeholder. Ships default ON with a
threshold of 5 (adjustable 1–20 in Settings → Content Filters, or off).

Scope
- Pure check (`HashtagSpamCheck`) + settings interface
  (`HashtagSpamSettings`) live in `commons/moderation/`, callable by
  Desktop, `amy` CLI, and (future) Android.
- JVM-backed `PreferencesHashtagSpamSettings` writes to the shared
  `java.util.prefs` node `com/vitorpamplona/amethyst/filters`, so `amy`
  and Desktop observe the same value automatically.
- `CollapsedSpamNote` placeholder in `commons/ui/note/` takes only
  primitive scalars so Android can adopt it without touching commons.
- Desktop wraps every `NoteCard` call site (FeedNoteCard, QuotedNoteEmbed,
  BookmarksScreen, 5 SearchResultsList sites) with a shared
  `SpamCheckedNoteRender` helper. Thread root notes auto-expand via
  `forceReveal=true`; replies still respect the filter.

Exemptions
- Long-form articles (kind 30023)
- Authors in the follow list plus self
- Repost wrappers check the inner event's tags via precomputed
  `note.replyTo`, falling back to `containedPost()`

Search UX fixes bundled in
- Removed the `#hashtag` → "Direct lookup" card. `QueryParser` already
  extracts `#xxx` into the query's hashtag filter, so typing `#bitcoin`
  now goes straight to filtered results.
- Search-result rows now trigger metadata loading via
  `subscriptionsCoordinator.loadMetadataBatched(authors)` and observe
  each user's metadata flow via a new `rememberDisplayData` helper, so
  display names + avatars refresh when kind-0 arrives from index
  relays. Same helper reused in Bookmarks.

Tests + docs
- 19 unit tests (check × 10, displayed-event unwrap × 4, prefs × 5),
  all green.
- Manual testing sheet with 16 scenarios at
  `desktopApp/plans/2026-06-29-hashtag-spam-filter-manual-testing-sheet.md`.
- Plan at `docs/plans/2026-06-29-feat-desktop-hashtag-spam-filter-plan.md`.
- Cross-client desktop feature backlog reference at
  `desktopApp/plans/_desktop-feature-backlog.md`.
