* Add Elecrow ThinkNode M8 variant scaffold (thinknode_m8) nRF52840 + SX1262 + 2.4" e-paper + ATGM336H-5NR32 GPS. All pins resolved from ThinkNode_M8_V0.3.sch; cross-checked against meshtastic/firmware#9181 (Elecrow V0.1 reference). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * Add Elecrow ThinkNode M8 board support (nRF52840/SX1262, 1.54in e-ink, ATGM336H GNSS, SC7A20, EC04 encoder) * Address review: keep the stored backlight level out of blanking, match only the SC7A20 WHO_AM_I byte, and transfer detents atomically * Use std::atomic for the press-and-turn detent counter so native builds compile * Drop the ThinkNode M8 LED_BUILTIN redefinition that warned on every translation unit --------- Co-authored-by: claude[bot] <41898282+claude[bot]@users.noreply.github.com> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
