CLI PATCHES MEMORY DOS AND FIXES PHANTOM BREAKING CHANGES

Shopify/cli shipped a critical security fix for stdin memory exhaustion and eliminated false-positive breaking change detection that was blocking legitimate PRs.

The `readStdinString` function in Shopify/cli was vulnerable to Denial of Service through unbounded memory consumption—attackers could exhaust heap by piping unlimited data to stdin [1]. This release introduces a hard 10MB limit, closing the attack surface immediately [2]. In parallel, the breaking-change detection pipeline was reporting phantom removals whenever main diverged from a PR's branch point [3]. PR #7466 shows the exact failure: the check flagged a field removal that never happened in the PR itself—main had added the field after branching [3]. That's now fixed by comparing against merge-base and scoping diffs to actual PR changes [3]. On the test side, replay.test.ts was replaced with real temporary directories instead of mocked filesystem calls, making the log discovery and sorting logic actually testable rather than testing the mocks themselves [4].
