Replace UF2 file copy to mass storage volume with direct picotool upload.
This avoids macOS "disk not ejected properly" warnings caused by the RP2040
resetting immediately after receiving the firmware.
- Use picotool (already installed by PlatformIO) for BOOTSEL detection
and firmware upload via USB
- Upload ELF directly with `picotool load -v -x` for real-time progress
- Remove platform-specific mass storage volume detection (macOS/Linux/Windows)
- Show helpful udev rules message on Linux permission errors
Add auto-detection of RP2040 BOOTSEL mass storage volumes (RPI-RP2) on
macOS, Linux, and Windows. Show detected volumes as upload targets with
a progress bar for UF2 file copy. Display helpful BOOTSEL instructions
when no RP2040 device is found.
- Add get_rp2040_mass_storage_volumes() to detect mounted RPI-RP2 volumes
- Add PortType.MASS_STORAGE and upload_using_uf2_copy() with progress bar
- Move ProgressBar to helpers.py for shared use
- Wait for USB-CDC serial port after upload for log output
- Auto-select single serial port for logs after mass storage upload
- Create firmware.bin.signed in post_build to fix nobuild upload target
- Show BOOTSEL tip when only OTA options are available
