Problem

The "Edit in VSCode Editor" feature does not work correctly on Windows.

Current Behavior

1. User clicks "Edit in Editor" button
2. Editor tab opens correctly
3. ❌ User saves the file, but nothing happens
4. ❌ Tab remains open, content is not applied to the form

Expected Behavior

1. User clicks "Edit in Editor" button
2. Editor tab opens correctly
3. ✅ User saves the file
4. ✅ Tab closes automatically, content is applied to the form

Root Cause

Path comparison between savedDoc.uri.fsPath and the stored filePath fails on Windows due to:

• Case sensitivity differences (e.g., c:\Users vs C:\Users)
• Path normalization inconsistencies with os.tmpdir()

Solution

1. Store temp files in .vscode/ directory instead of os.tmpdir() for better path consistency within the workspace
2. Normalize file paths using vscode.Uri.file(filePath).fsPath before comparison
3. Add tmp- prefix to temp file names for clarity (e.g., tmp-cc-wf-studio-xxx.md)

Changes

File: src/extension/commands/text-editor.ts

• Added getTempDirectory() function that prefers .vscode/ in workspace, falls back to os.tmpdir()
• Use vscode.Uri.file(filePath).fsPath for cross-platform path normalization
• Changed temp file naming from cc-wf-studio-xxx.md to tmp-cc-wf-studio-xxx.md
• Updated all path comparisons to use normalized path

Impact

• ✅ Fixes Windows compatibility issue
• ✅ No breaking changes for macOS/Linux
• ✅ Temp files are automatically cleaned up after editing

Testing

• Manual E2E testing on Windows - save detection works correctly
• Manual E2E testing on macOS - continues to work as expected
• Code quality checks passed (format, lint, check, build)
