* feat: add Raspberry Pi Pico 2 + W5500 + E22-900M30S variant
Adds community variant for Raspberry Pi Pico 2 (RP2350, 4 MB flash)
with external WIZnet W5500 Ethernet module and EBYTE E22-900M30S LoRa
module (SX1262, 30 dBm PA, 868/915 MHz).
Key details:
- LoRa on SPI1: GP10/11/12/13 (SCK/MOSI/MISO/CS), RST=GP15,
DIO1=GP14, BUSY=GP2, RXEN=GP3 (held HIGH via SX126X_ANT_SW)
- W5500 on SPI0: GP16/17/18/19/20 (MISO/CS/SCK/MOSI/RST)
- SX126X_DIO2_AS_RF_SWITCH: DIO2→TXEN bridge on module handles PA
- SX126X_DIO3_TCXO_VOLTAGE 1.8: TCXO support via EBYTE_E22 flags
- DHCP timeout reduced to 10 s to avoid blocking LoRa startup
- GPS on UART1/Serial2: GP8 TX, GP9 RX
- Reuses WIZNET_5500_EVB_PICO2 code paths for Ethernet init

* pico2_w5500_e22: rename define and address review feedback
Rename WIZNET_5500_EVB_PICO2 to PICO2_W5500_E22 so the variant-specific
define matches the variant directory name and isn't confused with an
on-board EVB SKU.
Review fixes from PR #10135:
- Gate the 10 s Ethernet DHCP timeout behind PICO2_W5500_E22 so other
Ethernet builds keep the default 60 s behavior; apply the same timeout
to reconnectETH() for consistency.
- Drop the unused -D EBYTE_E22 flag; EBYTE_E22_900M30S already selects
TX_GAIN_LORA / SX126X_MAX_POWER in src/configuration.h.
- Rewrite "on-board W5500" comments to describe the external module.
- Correct README TX_GAIN_LORA value (7, not 10) and drop the EBYTE_E22
row.
* fix(pico2_w5500_e22): drop DEBUG_RP2040_PORT=Serial
The arduino-pico framework hooks _write() when DEBUG_RP2040_PORT=Serial
is set and dumps raw debug bytes onto USB CDC, corrupting any binary
protobuf stream sent through StreamAPI (e.g. `meshtastic --port COMx`).
The variant excludes BT and WiFi, so the primary client transport is
Ethernet TCP via ethServerAPI — unaffected — but users who configure
the node over USB serial would see protobuf decode failures from
debug-byte interleaving. Removing the flag restores clean USB CDC.
Debug output can still be enabled per-build by adding -D DEBUG_RP2040_PORT=Serial1
to redirect to UART0 instead of USB CDC.
* style(pico2_w5500_e22): apply trunk fmt — fixes Trunk Check
- variant.h: clang-format 16.0.3 (drop manual #define alignment)
- README.md: prettier + add `text` language to fenced code blocks (markdownlint MD040)
- wiring.svg: svgo optimization
Resolves the Trunk Check Runner failure on this PR (3 unformatted
files + 8 markdownlint issues). No functional changes.

* refactor(pico2_w5500_e22): address review — move to rp2350/diy, generic guards
Maintainer feedback from NomDeTom on PR #10135:
- Move the variant from variants/rp2350/ to variants/rp2350/diy/ to
distinguish DIY from prebuilt boards (matches the variants/*/diy/
pattern; still discovered via the existing variants/*/diy/*/platformio.ini
glob in the root platformio.ini).
- Replace the board-name macro PICO2_W5500_E22 in shared code with a
generic capability macro USE_ARDUINO_ETHERNET, defined from variant.h.
DebugConfiguration.h / ethServerAPI.h / ethClient.cpp no longer
reference a board name.
- Drop the architecture.h hook entirely: variant.h now defines PRIVATE_HW,
which the existing `#elif defined(PRIVATE_HW)` branch already handles.
No functional change. Build verified: pico2_w5500_e22 SUCCESS
(RAM 19.2%, Flash 28.1%).
