Review follow-up for #72.
- releaseAssetName() takes ConfigSettings::chipModel ("", "s3", "c3", "c6"),
so GitOTA no longer keeps its own chip switch. C3 keeps its name for when
the build comes back.
- hasFS is set only when this board's own LittleFS image is in the release.
isFsAsset() is gone; it also matched the old unsuffixed littlefs.bin, which
the updater no longer asks for.
- releaseAssetName() returns void: no caller checked the result and every
name fits currentFile.
- Both manual-upload hints name this board's file.
- KNOWN_ISSUES: the "Main" install can't work, the repo holds no .bin files.
