Chained on top of the memory-impact fix to exercise it in real CI.
Changed components and their base-test platforms:
- const: variant-only test (test-display.esp32-s3-idf.yaml, no base test).
--base-only cannot build it, so the fix must exclude it; it only injects
an esp32-s3-idf platform hint.
- shelly_dimmer: base test esp8266-ard (real C++).
- daikin: base test esp8266-ard (real C++), the working third component.
Without the fix, the esp32-s3-idf hint (and const's variant counted as a
supported platform) selects esp32-s3-idf, which none of the three can build
under --base-only, yielding 0 builds and a failed memory extraction. With the
fix, const is excluded, the unbuildable hint is ignored in favor of the common
esp8266-ard platform, and shelly_dimmer + daikin generate memory impact.
