refactor: include hidden dotfiles folders in file picker search

[Abhijay007]

closes #6211

PR description:

Refactor the file picker to include hidden configuration folders in search results. Previously, all files and folders starting with . were excluded, making it impossible to reference important configuration files like GitHub workflows, VS Code settings, and other dotfiles.

Changes made

• Added allowlist for hidden directories: Created allowedHiddenDirs array containing important configuration directories:

  • .github - GitHub workflows and actions
  • .vscode - VS Code settings
    etc .....

• Updated filtering logic: Modified the file picker to check if hidden items are in the allowlist before skipping them, instead of blanket-excluding all dotfiles

• Removed from skip list: Removed .vscode and .idea from skipDirs since they're now explicitly allowed

• Documentation update: Updated file management guide to document the new hidden folder support

Type of Change

• Refactor / Code quality

hmm, is there a different approach that will allow all hidden directories, not just a hardcoded list?

[Abhijay007]

It's like we skipped some of the files, just like we did before. I am not sure if we should allow all of them

[angiejones]

why skip?

[Abhijay007]

just like before, we skipped some of the dotfiles and others for security purposes, like .git and system, etc if we want, we can allow all

[alexhancock]

i think just include them all, as this is for when the user is selecting right?
