Enhance collaboration and selection management in IDE

[Praveen-R-2518]

This pull request introduces several improvements to collaborative editing, file tree refresh logic, and cross-platform path normalization. The most notable changes enhance the reliability and accuracy of real-time collaboration, ensure the file tree updates correctly when triggered, and improve file and tab management across different operating systems.

Collaborative Editing Enhancements

• Improved synchronization when a new client joins: Existing clients are now prompted to send their full state via an empty SyncStep1 message, and awareness updates are requested, ensuring all participants have the latest document and presence information.
• Monaco editor binding now uses pushEditOperations instead of setValue to update content, preventing cursor jumps and preserving undo history. Awareness and cursor selection logic is more robust, including proper disposal and clearing of stale selections on binding destroy.
• Collaborative file save operations are now broadcast to all peers, so saving a file locally triggers automatic saves on other clients in the session.
• Improved initialization and rebinding of Monaco bindings to Y.Text, distinguishing between new and existing collaborative documents for proper content synchronization.
• Awareness selection positions now use the optional -1 parameter for compatibility and accuracy.

File Tree Refresh and UI Improvements

• Added a refreshTrigger prop to the file tree and its nodes, enabling programmatic refreshes of directory contents and closing context menus or creation states after refresh.
• File tree node activation now normalizes path separators, ensuring correct highlighting and selection across platforms.

Path Normalization and Tab Management

• All file paths are normalized to use forward slashes, preventing inconsistencies and bugs when managing tabs, opening files, and handling file operations across Windows, macOS, and Linux.
• When files or directories are deleted, affected tabs are now removed (rather than just marked as deleted), and the active tab switches to the next available tab if the current one is deleted.
• When a file is deleted, its collaborative content is cleared with an explicit flag to ensure proper synchronization.

Editor Behavior Improvements

• The Monaco editor now keeps the current model when switching tabs, preventing unnecessary re-creation and improving performance and user experience.
• End-of-line normalization is enforced for collaborative Monaco models, ensuring consistent line endings.

Miscellaneous

• The remoteCreatesRef is removed, simplifying file operation tracking logic.
• Collaborative file content retrieval now returns the content regardless of whether it's empty, improving compatibility with new files.

These changes collectively improve the reliability, usability, and cross-platform compatibility of collaborative editing and file management in the application.
