fix(ios): prefer native CocoaPods before Rosetta

[aleclarson]

On Apple Silicon, a successful arch -x86_64 pod --version probe only proves Rosetta is available. CocoaPods is commonly a script, so the probe can succeed even when native execution works. The CLI then unnecessarily forces pod installation through Rosetta.

Probe the selected pod or sandbox-pod executable natively first. Use Rosetta only when native execution fails with a CPU-format error; preserve unrelated probe failures.

Validation: CLI build passes; all 121 test files pass (1,894 tests, 9 skipped). Added Apple Silicon regression cases for native execution with Rosetta available, CPU-error fallback, sandbox-pod, and unrelated failures. A local pnpm patch provides the fix to nativescript 9.1.1 immediately. The patched installed service successfully ran native pod install (16 pods).

App-level prepare stops at an unrelated missing Octane Children export. Native pod installation still excludes arm64 simulators for the installed MLKit pods: MLKitVision 10.0.0 explicitly declares these exclusions, and its arm64 archive objects target iOS devices rather than simulators. This PR corrects CLI architecture selection; it does not add simulator support to those vendored frameworks.

📝 Walkthrough

Walkthrough

On macOS ARM64, executePodInstall probes the configured CocoaPods tool natively. It uses Rosetta only when the probe reports “Bad CPU type in executable” or “Exec format error.” Tests cover pod, sandbox-pod, native execution, fallback, and unrelated probe errors.

Changes

CocoaPods ARM64 execution

Layer / File(s)	Summary
Probe configured tool and select execution mode lib/services/cocoapods-service.ts, test/cocoapods-service.ts	The service probes the configured tool natively and uses Rosetta for the specified architecture errors. Tests cover both tools, native installs, fallback, and propagation of unrelated probe errors.

Then lets the native path run on.
If CPU errors bar the way,
Rosetta helps the tools obey.
Two tools hop through the test parade!}

71-76: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Guard err.message in the probe catch block.

this.$childProcess.exec rejects with whatever child_process.exec supplies. That is normally an Error. If a non-Error value is thrown, err.message is undefined, and .test(undefined) tests the string "undefined". The code then rethrows the original error, so the behavior is safe. The cause is unclear if err is null or undefined, because the property access throws a TypeError that hides the original failure.

Use an instanceof Error check before reading message.

Proposed fix

 			} catch (err) {
+				const message = err instanceof Error ? err.message : String(err);
 				if (
-					!/Bad CPU type in executable|Exec format error/i.test(err.message)
+					!/Bad CPU type in executable|Exec format error/i.test(message)
 				) {
 					throw err;
 				}
