Greptile Summary

This PR removes the getEnv helper method from Platform.php and deletes its corresponding test file. The change is internally clean — there are no remaining callers of getEnv anywhere in the repository.

• src/Platform/Platform.php: getEnv method removed; the rest of the class is untouched.
• tests/unit/GetEnvTest.php: associated test deleted alongside the implementation.
• The only noteworthy point is that this is a public method removal on a published library. Downstream consumers who call $platform->getEnv(...) will encounter a fatal error after upgrading. Depending on the project's versioning policy, this warrants a semver major bump rather than a fix: patch label.

Confidence Score: 5/5

Safe to merge — the removal is internally consistent with no remaining usages; only consideration is the semver versioning convention for the release.

The single finding is a P2 style/process note about the semver implications of removing a public API method; it does not represent a bug, data issue, or correctness problem within the repository code itself.

No files require special attention beyond the versioning note on src/Platform/Platform.php.

Important Files Changed

Filename	Overview
src/Platform/Platform.php	Removes the public getEnv method; no internal usages remain, but this is a breaking API change for library consumers.
tests/unit/GetEnvTest.php	Test file for the removed getEnv method is cleanly deleted alongside the implementation.
