CI/CD: Duplicate issue detector and auto labelling as "Duplicate" #287
Description
Problem: Contributors must manually search through many existing issues before creating a new one, which is time-consuming and often leads to duplicate reports.
How: Add automated duplicate detection using a GitHub bot (semantic matching) and a lightweight GitHub Action to flag similar existing issues on creation.
Impact: it will mark that issue duplicate so that maintainer don't have to waste too much time
Notes: Automation will only suggest possible duplicates (no auto-closing, or auto-closing depends on choice) .
