Re-applies changes that were accidentally discarded during a prior dry-run cherry-pick reset (git checkout -- .). - PR #1005: Use HalPowerManager for battery percentage (uint16_t return type, remove Battery.h, update theme files) - PR #1010: Fix dangling pointer in onGoToReader() - PR #1003: Render image placeholders while waiting for decode (adds isCached, renderPlaceholder, renderTextOnly, countUncachedImages, renderImagePlaceholders) Co-authored-by: Cursor <cursoragent@cursor.com>
