Bug: "New from Template" overwrites existing files (Data Loss)

[sudo-Harshk]

Hi! I pulled v0.5.0 and ran a stress test on the new Templates feature.

Overall, the implementation is excellent and handles most edge cases gracefully! However, I found one Critical Data Loss issue that needs immediate attention.

Critical Bug: Silent Overwrite (Data Loss)

The "New from Template" action creates the file immediately without checking if a note with that name already exists.

Steps to reproduce:

1. Create a note named Data and add some unique text.
2. Click + New -> New from Template.
3. Select any template.
4. Enter the name Data (same as step 1).
5. Click Create.

Result: The original Data.md is silently overwritten with the template content. The user's original text is lost permanently.
Expected: The system should alert "File already exists" or auto-rename to Data-1.md.

Thank you! It should be addressed in the latest release:

I pulled the latest main and re-ran the test case.

Verified: The system now correctly detects the duplicate name and shows an alert to the user, preventing the accidental overwrite.
