Update the root and eleven component composer manifests for the 0.11 release: version 0.11.0, dev-main alias 0.11.x-dev, homepages 0.11.x, and venusian-surface/*, venusian-voyager/* and gpio/contracts requirements at ^0.11.0.

PHP constraint is now ~8.4.27||^8.5.12 (the framework's patched floor). ext-fb, ext-rasterize and ext-imgdec suggestions accept ^0.10.0|^0.11.0, and scrapyard-io/framework is suggested at ^0.11.0. Driver suggestions for jovian and dept-of-scrapyard-robotics stay at ^0.10.0 until they move.

Also remove the tracked .idea project files and add a 0.11.0 entry to .okf/log.md. No API change.
