* fix(esp32): skip RTC timer wake on user shutdown Do not arm esp_sleep_enable_timer_wakeup when msecToWake is portMAX_DELAY (UI shutdown), matching nRF52 system_off semantics. fix(rak_wismesh_tap_v2): Tag OCV curve and 16MB partition Add OCV_ARRAY matching WisMesh Tag for accurate SOC. Use 16MB flash partition scheme for TAP V2 hardware. Co-authored-by: Cursor <cursoragent@cursor.com> * Trunkt * Add RAK WisMesh Repeater Mini V2 and HP variants Introduce rak_wismesh_repeater_mini (RAK4631) and rak_wismesh_repeater_mini_hp (RAK3401) with low-VDD System OFF. Skip LPCOMP battery wake on user-initiated shutdown to avoid immediate reboot near the LPCOMP threshold; keep LPCOMP for brownout-driven shutdown via variant_enableBatteryLpcompWake. * docs(variants): update RAK BOM numbers for Repeater Mini V2 & HP * chore: run trunk fmt --------- Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
