The dashboard's source-routed runner ships idedata.json with bare
basenames in prog_path and extra.flash_images[*].path (the receiver's
build-host absolute paths don't resolve on the offloader, and the
in-memory Web Serial consumer keys by basename). Without this change,
the dashboard would have to write a fresh idedata.json into the staging
tmpdir on every install just to flip basenames to absolute paths.
Resolve relative paths in the prebuilt idedata against CORE.prebuilt_dir
so both the dashboard's wire format and a hand-built directory with
absolute paths work. cc_path is left alone because it points at a
PlatformIO toolchain binary outside the prebuilt dir; the offloader's
own PIO install provides the matching binary.

Adds a --prebuilt-dir flag to esphome upload that points the per-platform
upload helpers at a directory of prebuilt artifacts shipped from a paired
build server, instead of re-deriving paths from the local build tree.
Covers every upload-dispatch shape:
- ESP32 / ESP8266 serial (esptool) reads firmware.bin + extras via the
prebuilt idedata.json the dashboard ships next to the artifacts.
- ESP32 / ESP8266 OTA (native API + web_server) reads CORE.firmware_bin,
CORE.partition_table_bin and CORE.bootloader_bin which now consult the
prebuilt-dir first.
- RP2040 BOOTSEL (picotool) falls back from the idedata ELF (absent in
the flat layout) to the prebuilt firmware.uf2.
- RP2040 serial / libretiny serial / OTA (PlatformIO upload -t nobuild)
point platformio at the prebuilt build tree via CORE.build_path so the
-t upload -t nobuild path finds platformio.ini and .pioenvs/<name>/.
