[ENGINEERING] Add main.rs backup file should be removed

[developerfred]

Problem

Found backup files in the repository that should be cleaned up:

• src/main.rs.bak
• tools/lsp/src/main.rs.backup

Why Remove

1. Causes confusion for developers
2. Not tracked in version control meaningfully
3. Can be recovered from git history

Recommendation

rm src/main.rs.bak
rm tools/lsp/src/main.rs.backup

Or if these are intentional backups, add them to .gitignore.

Priority

Low - Cosmetic issue

Labels

• engineering
• cleanup
