Repository cleanup: remove duplicate files, fix import order, standardize env template name

[Copilot]

Housekeeping changes to remove merge/copy artifacts, fix a Python best-practice violation, and standardize the environment template filename.

Description

Removes duplicate files with no unique content, consolidates the better copyright into the canonical LICENSE, moves a misplaced import to the top-level, and renames env.example to the widely-recognized .env.example convention with all references updated.

Changes:

• Deleted README (2).md — contained only a single typo'd heading; zero unique content
• Deleted LICENSE (2) — duplicate; merged its more accurate copyright (2025 Itesh Bisht) into canonical LICENSE, replacing 2024 Document Processing Platform
• setup.py — moved import time from inside setup_database() body to top-level imports (PEP 8)
• env.example → .env.example — standard dotenv convention; updated all references in setup.py, QUICKSTART.md, and PROJECT_SUMMARY.md (CONTRIBUTING.md already used .env.example)

Note: Repository rename (Dcoument- → Document-) requires admin action in the GitHub UI.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Performance improvement
• Refactoring (no functional changes)
• Test addition or update
• CI/CD improvement

How Has This Been Tested?

• Manual testing

Verified setup.py parses cleanly (ast.parse). Confirmed .env.example is present and all string references to env.example are updated across the repo.

Test Environment:

• OS: Ubuntu 20.04
• Python Version: 3.x

Additional Notes

The .env.example rename is non-breaking for runtime — the file is not loaded automatically by any framework here; it's only copied manually via setup.py or the instructions in QUICKSTART.md.

Breaking Changes

None.

Performance Impact

None.

Security Considerations

No secrets were added. SECRET_KEY placeholder in .env.example remains a clearly-labeled dummy value (your-secret-key-here-change-in-production).

Bug Fixes and Cleanup

1. Fix repository name typo

• Recommend renaming the repository from Dcoument-Processing-Platform to Document-Processing-Platform for professionalism and discoverability. (This will require manual intervention or admin rights in GitHub UI.)

2. Remove duplicate/copy artifact files

• Delete extra files such as README (2).md, LICENSE (2), and any similar merge/copy artifacts from the root.

3. Move any good content from duplicates (if needed)

• If there are any lines or sections in the duplicate files that are missing from the canonical ones, merge them and consolidate the best content.

4. Refactor setup.py subtlety

• Move import time statement to the top of setup.py to follow Python best practices for imports.

5. Add/clarify .env.example

• If not present, create .env.example file in the root, backend, or frontend directory as appropriate, with placeholder/demo variables based on the standard dev environment for this stack.

6. Audit for other accidental files/merges

• Remove or clarify any other duplicate or merge-conflict files in project root as appropriate.

7. README cleanup

• Confirm README.md references the correct name throughout and that setup instructions match the repo structure.
