#7115 added cross-package calls new in 4.4 — getStateOptionsRepositoryMethod()
in api-platform/state and the repositoryMethod constructor argument in
api-platform/doctrine-common — that 4.4 provider code invokes. The old
^4.2/^4.3 sibling floors let `composer update --prefer-lowest` pull releases
lacking these symbols, so the per-component lowest CI jobs failed with
"undefined method" / "unknown named parameter".

Floor all api-platform/* inter-package constraints at ^4.4. The @alpha
stability flag is required because the subpackages set minimum-stability:beta,
under which a plain ^4.4 would not match the 4.4.0-alpha prereleases. Revert
to plain ^4.4 once 4.4.0 stable ships.
