On ESP32-C3 with USB CDC, Serial.printf() blocks indefinitely when USB is not connected. This caused device freezes when booted without USB. Solution: Call Serial.setTxTimeoutMs(0) after Serial.begin() to make all Serial output non-blocking. Also added if (Serial) guards to high-traffic logging paths in EpubReaderActivity as belt-and-suspenders protection. Includes documentation of the debugging process and Serial call inventory. Also applies clang-format to fix pre-existing formatting issues.
