fix: applying AI code fixes on Windows [IDE-395]

[ShawkyZ]

Description

• use fspath instead of path.
• parse file path Uri using vscode.vscode.Uri.file(filePath) instead of vscode.Uri.parse(filePath)
  Difference is

vscode.Uri.file(filePath).fsPath
'c:\\Users\\user\\work\\project-with-vulns\\copy.ts'
vscode.Uri.parse(filePath).fsPath
'\\Users\\user\\work\\project-with-vulns\\copy.ts'

Checklist

• Tests added and all succeed
• Linted
• CHANGELOG.md updated
• README.md updated, if user-facing
