fix(ci): keep hosted unit tests offline and deterministic - #9

- Skip Firestore-backed stores when the app runs as a unit-test host. Multiple parallel hosts share one LevelDB cache and abort inside FirestoreClient::Initialize with "Failed to open DB". - Disable parallel test execution in the CI test step and the shared scheme; app-hosted parallel runners intermittently exit before tests. - Inject diff safety arguments for every diff-producing read-only Git command, not just diff*. - Verify the reviewed remote tip before a force-push undo/redo, since --force-with-lease is skipped when the push is a no-op. - Trim the dangling quote when recovering text from an output-limited JSON response. - Align four unit tests with current behavior (billing .none, JSON escaping, PR content header, directory URL).

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Preserve a terminal backslash in recovered text.
If the truncated text ends with \, JSON leaves \\ after dropLast(). The current replacements do not decode that pair, so the recovered answer contains two backslashes instead of one.
Decode supported JSON escapes in one pass, including \\, and add a regression test for a terminal backslash.

Why CI failed
Buildwas green because the scheme's Build action only builds the app target;Testalso builds themacgitTestsbundle and then runs it. Two separate problems were stacked:macgitApp.init()always configured Firebase and built the Firestore-backed stores. Every test runner opened the shared persistent LevelDB cache at~/Library/Application Support/firestore/.... Withparallelizable = YES, several hosts contended for the same lock, and one aborted insideFirestoreClient::Initialize(HARD_ASSERT(created.ok(), "Failed to open DB: ...")) →Early unexpected exit ... abort() called→ exit 65.2fcba765).Changes
