Several problems with this feature came up while testing 4.3.0-rc1.
These include both broken stdlib distributions and regressions in our
implementation of the feature since CMake 4.2.
Revert commit 70c1f0f43d (Experimental: Remove import std experimental
gate, 2026-02-04, v4.3.0-rc1~61^2) except for its incidental fixes.
Remove the 4.3 release notes related to `import std`.
Rotate the experimental gate's UUID.
