Improve file waiting mechanism in EmulatorFileSystem

This PR enhances the waitForFile method in the EmulatorFileSystem class to be more efficient and reliable when waiting for emulator files to finish writing.

Changes

• Added stat method: New helper method that safely wraps FS.stat() with error handling
• Refactored waitForFile logic: - Replaced expensive buffer content reading with lightweight file size checking
• Increased max retries from 30 to 120 for better handling of slow file systems - Adjusted timing from max 1000ms to max 500ms delays for more responsive checking - Simplified completion detection to wait for file size stabilization

Benefits

• Performance: Significantly faster file polling using stat() instead of full content reads
• Memory: Reduced memory usage by eliminating buffer storage during polling
• Reliability: More robust file completion detection through size comparison
• Compatibility: Better handling of various file system speeds and file sizes

Thanks for merging this.
I wonder how can I get some reach for Koin Player? this would help me find contributors as well. How did you do this?

I'm not quite good at this too and here's a general guide I used to learn from: https://opensource.guide/finding-users/ . This can be the hardest part of an open source project, way more difficult than writing code. And there's a significant element of luck involved.
