Improve heap management in EPUB rendering

Fix CPU pinning by tracking buildHeapPaused state when background build is blocked. Re-check heap gate after acquiring lock to handle race conditions where rendering expands glyph buffers. Refine plane buffer allocation to check both free heap and max contiguous block, preventing fragmentation issues that could cause OOM during page renders. Skip async refresh for image pages since they use blocking double-FAST path.
