Swimchain Android v0.1.8-alpha (mainnet — full-bleed feed media)

Feed images now run edge-to-edge like a modern mobile feed: full-width media with a capped 4:5 crop for tall images, and an Instagram-style swipe carousel (snap, dots, n/N counter) for multi-image posts. From PR #102. App version 0.1.1 / versionCode 1001 — installs as an update over previous builds.
