nrobi144 de2c970e3e feat(desktop): Follow Packs (NIP-51 kind 39089) discovery and follow flow
Adds a Follow Packs experience to Amethyst Desktop:

- New "Discover" sidebar destination with featured-pack hero, hashtag chips
  driven by NIP-12 `t` tags, a 3-up "From the pack" notes feed, and a
  right-rail of mini pack thumbnails.
- New "Follow Packs" launchable column (App Drawer + Discover "Browse all")
  with multi-field search across title, description, creator name/npub,
  and `t` tags.
- Pack detail overlay (read-only) with per-member Follow/Unfollow buttons
  that reflect the live kind-3 state, plus pack-level Follow all /
  Unfollow all with a dedupe-aware confirm dialog ("Follow N new (M
  already followed)").
- Bulk follow / unfollow batched into a single kind-3 publish via new
  `FollowActions.buildUnfollowBatch` and `Kind3FollowListState.follow/
  unfollow(users: List<User>)`. The mutating call sites are Mutex-
  protected against concurrent races.
- naddr → 39089 references in notes render as a rich inline card with
  avatar stack + Follow all CTA. Cache miss triggers a one-shot
  subscription; empty / deleted packs render minimal states.
- Shuffle button rotates both the featured pack and the gallery,
  excluding the last 5 shown.
- Pack image fields render via Coil `AsyncImage` with a deterministic
  gradient fallback.

Protocol additions:
- Quartz: `FollowListEvent.hashtags()` convenience accessor.

Bug fixes wrapped into the feature:
- `DesktopLocalCache.consumeContactList` now also loads the event into
  `addressableNotes` so `Kind3FollowListState.getFollowListEvent()`
  returns the user's actual kind-3. Without this, every bulk follow
  silently replaced (rather than appended to) the contact list.
- Added Material Symbols `Shuffle` codepoint and regenerated the
  bundled subset font (still 432 KB).
