vc=33: persistent feed cache + strawcore avatar fix (via strawcore-core)

Browse source 
Channel-avatar issue and the sluggish-load issue both addressed.

strawcore-core (Sulkta-Coop/strawcore @ 7c71511) — separate repo,
already committed + pushed:
  Channel parser was only pulling avatar from the legacy
  c4TabbedHeaderRenderer branch. The newer pageHeaderRenderer
  (most channels with a 2024+ refreshed header — including WTYP)
  was returning empty avatars. Added a deep-nested ViewModel walk
  for pageHeaderRenderer, plus a metadata.channelMetadataRenderer
  .avatar.thumbnails[] backfill. WTYP and other re-headered channels
  should now show their icon.

Persistent feed cache (data/FeedCacheStore.kt):
  New SharedPreferences-backed JSON store. ~225 KB at the upper
  bound (30 subs * 30 items * ~250 bytes), well within SP's comfort
  zone. Survives process death.

SubscriptionFeedViewModel:
  Hydrates from FeedCacheStore on init. The Subs tab now paints
  cached items in one frame on cold start, then refreshes stale
  channels in the background.
  Persists the cache after each successful refresh via Dispatchers.IO.
  Per-channel TTL bumped 10min → 30min (disk cache amortizes the
  cost; stale-from-disk + background-refresh feels like instant).
  Per-channel timeout 15s → 10s (slow channel rides cached value
  instead of stalling the batch).
  Parallelism 8 → 12 (less network-bound now that UI doesn't wait
  for first byte).

StreamItem now @Serializable so the cache can encode it.
FeedCache.init wired into StrawApp.onCreate alongside the other
SharedPreferences-backed stores.
