Refs: nodejs#60859 Add a new section to the fs.watch documentation explaining that rapid file operations may cause missed or coalesced events due to underlying OS file watching mechanisms. Provide recommendations for applications requiring reliable event detection, including using third-party libraries like chokidar, fs.watchFile for critical files, or implementing debouncing logic.

This PR improves the
fs.watchdocumentation by adding a new section explaining the behavior of file watching during rapid file operations.Changes
Added a new "Event Reliability with Rapid Operations" section to the
fs.watchcaveats that:chokidarfs.watchFile()for critical individual filesMotivation
Issue #60859 reported that
fs.watchmisses events during rapid file operations. This is expected behavior due to OS-level limitations, not a Node.js bug. This documentation improvement helps users understand this limitation and provides alternative solutions.
