WiFi/LWIP/netif teardown scatters long-lived allocations across the heap, leaving ~50KB of contiguous space unrecoverable without a reboot. Reboot the SoC on exit from any wifi-using activity to guarantee a clean heap. An RTC_NOINIT flag survives the reboot and tells setup() to skip the boot splash and route the user back where they came from: - File transfer / Calibre / OPDS / Font download -> home - KOReader sync -> currently-open EPUB Activities check WiFi.getMode() before rebooting, so backing out of the network mode menu without joining doesn't trigger a cycle. KOSync also esp_wifi_stop()s after the sync result so the radio is off while the user reads it; full teardown happens at the reboot. ## Additional Context The silent reboot skips the booting splash screen - it visibly looks like a screen refresh. This does cause a disconnection/reconnection blip for developers actively pulling logs over serial, but `pio device monitor` and the like successfully reconnect and feed in the early boot serial. as an example: ``` [256676] [DBG] [ACT] Exiting activity: KOReaderSync [256706] [DBG] [MAIN] Silent restart (target=reader) ESP-ROM:esp32c3-api1-20210207 Build:Feb 7 2021 rst:0xc (RTC_SW_CPU_RST),boot:0xf (SPI_FAST_FLASH_BOOT) Saved PC:0x403872bc SPIWP:0xee mode:DIO, clock div:1 load:0x3fcd72a0,len:0x990 load:0x403cbf10,len:0xac8 load:0x403ce710,len:0x4d28 entry 0x403cbf10 [22] [INF] [MAIN] Hardware detect: X4 [29] [SD] SD card detected [43] [DBG] [CPS] Settings loaded from file [58] [DBG] [KRS] Loaded KOReader credentials for user: jeremydk [69] [DBG] [OPS] Loaded 1 OPDS servers from file [69] [DBG] [UI] Using Lyra theme [70] [DBG] [MAIN] Starting CrossPoint version 1.2.0-dev-detached-bde75787 ...
