fix: switch to promises to prevent locking on windows os

Key Changes:

• closes 🚨 [BUG] - Windows OS performance with fsspec file locking #4 and issues reported by Amr / Sytten
• aims to also close Using fs on the caido project database is causing weird issues on windows caido/caido#1761 if this is a plugin-issue but is believed to be on the caido side, not the plugin

Changed:

1. Replaced synchronous imports with async versions:
   - accessSync, readdirSync, statSync → access, readdir, stat from fs/promises
2. Updated pathExists function:
   - Now returns Promise instead of boolean
   - Uses await access() instead of accessSync()
3. Refactored directory scanning:
   - scanDirectory is now async and returns Promise
   - Uses await readdir() instead of readdirSync()
   - Uses await stat() instead of statSync()
   - Added await for recursive calls to scanDirectory()
4. Updated function calls:
   - Added await when calling pathExists()
   - Added await when calling scanDirectory()

@Sytten @amrelsagaei could i ask if you had 5 mins for a quick PR review on this please? tested and works in my VM but i don't have Windows hardware

Generated Summary

• Converted file system operations from synchronous to asynchronous by replacing "fs" functions with corresponding functions from "fs/promises".
• Updated the pathExists function to use async/await, ensuring proper handling of file existence checks.
• Modified getWorkspaceFiles to utilize the new async functions for directory reading and file statistics, including within the recursive scan of directories.
• Adjusted conditional checks and logging to reflect asynchronous status and results.
