Claude d57f8c18c6 feat: first-class NIP-32 hashtag labels on posts and in the hashtag feed
Let users tag any post with a hashtag via a NIP-32 kind 1985 label event
(using the `#t` tag-association namespace), and surface follow-labeled
posts in the hashtag feed.

quartz:
- LabelEvent.buildHashtagLabel() + HASHTAG_NAMESPACE ("#t") and
  hashtagAssociations() to build/extract hashtag-association labels.

commons:
- Note now carries a `labels` reverse-reference map (hashtag -> labeler
  notes) with addLabel/removeLabel and a NoteFlowSet.labels flow,
  mirroring reactions/reports.

amethyst:
- LocalCache consumes LabelEvent, attaching hashtag labels to their
  target notes and re-notifying feed observers for already-cached
  targets.
- Account.createLabelHashtagEvent/labelHashtag/consumeLabelEvent and
  AccountViewModel.labelWithHashtag (tracked + direct broadcast).
- Overflow "⋯" menu gains an "Add hashtag" action backed by a new
  AddHashtagLabelDialog.
- HashtagFeedFilter also accepts posts a followed user labeled with the
  hashtag; a new label sub-assembler subscribes to kind 1985 by `#l`
  and fetches missing label targets.
- Hashtag feed shows an attribution banner ("#tag added by @user") above
  follow-labeled posts via a custom RefresheableFeedView onLoaded.
