test(e2e): cover TypeScript 7 auto inputs

[wan9chi]

Motivation

TypeScript 7 executes a native compiler. Automatic input tracking observes its source reads on Linux and Windows, while macOS library validation can prevent the fspy dyld interposer from loading. Hosted macOS CI machines disable System Integrity Protection, so the macOS case must make that restriction explicit to remain deterministic.

Summary

• Add a TypeScript 7 fixture for automatic input inference.
• Verify a source change invalidates the cache on non-macOS targets.
• Verify macOS cannot infer the native compiler source reads when library validation is required and therefore replays the cached result.
• Copy the native compiler into the staged fixture and sign that copy with the runtime and library-validation flags, leaving the installed dependency untouched and covering SIP-disabled CI.
• Keep the dependency-backed cases opt-in with the existing ignored-test mechanism.
