Reverts the frame header synchronization added in #14135 and #14136 in favor of a simpler fix: increasing MAX_LINE_LENGTH so that the existing footer-based resynchronization can recover after losing sync. Both components already check for frame footers at every byte position, which naturally resyncs the parser. The problem was that the buffers were sized exactly to fit the largest frame, so a desynced parser's footer could land at the overflow boundary and get discarded. Increasing the buffer by 4 bytes (footer size) ensures the footer always lands inside the buffer. - ld2450: 41 -> 45 (zone query response = 40 bytes + 1 null + 4 footer) - ld2410: 46 -> 50 (engineering data frame = 45 bytes + 1 null + 4 footer) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
