💡 What: Optimized file reads by providing the encoding utf8 directly to fs.readFileSync instead of calling .toString() on the returned Buffer.
🎯 Why: Calling .toString() on a Buffer allocates unnecessary intermediate objects in memory, which increases Garbage Collection overhead. Passing the encoding directly is more efficient.
📊 Impact: Minor memory optimization during internal CLI operations and builds, improving speed marginally by avoiding unnecessary garbage collection.
🔬 Measurement: Verify tests across @expo/cli, @expo/config-plugins, and @expo/prebuild-config pass successfully, ensuring no behavioral regressions.


PR created automatically by Jules for task 9600845382343440780 started by @vishnu-madhavan-git

Refactor instances of `fs.readFileSync(path).toString()` to `fs.readFileSync(path, 'utf8')` to avoid unnecessary intermediate Buffer allocations and reduce GC overhead.
