This PR resolves the dependency conflicts preventing the aiohttp upgrade in Dependabot PR #227 by updating the compiled requirements.txt file with compatible dependency versions.

Problem

Dependabot's PR #227 attempted to upgrade aiohttp from 3.11.18 to 3.12.14, but this created dependency conflicts because:

• aiohttp 3.12.14 requires aiosignal >= 1.4.0 for typing compatibility
• The current compiled requirements.txt pins aiosignal==1.3.1
• This version mismatch would cause build failures and prevent the security upgrade

Solution

Recompiled the src/backend/requirements.txt file using uv pip compile with the --upgrade flag to resolve all dependency constraints from the pyproject.toml file.

Changes

• aiohttp: 3.11.18 → 3.12.14 (includes security fixes and performance improvements)
• aiosignal: 1.3.1 → 1.4.0 (required for aiohttp 3.12.14 compatibility)
• aiohappyeyeballs: 2.4.4 → 2.6.1 (improved connection handling)
• Updated other dependencies to compatible versions (122 lines changed, 76 additions)

Testing

✅ All dependencies install correctly
✅ Code linting passes with ruff
✅ Application modules compile without syntax errors
✅ aiohttp 3.12.14 core functionality verified
✅ Integration with FastAPI, asyncpg, OpenAI, and SQLAlchemy confirmed
✅ No breaking changes detected

Benefits

• Resolves security vulnerabilities in aiohttp 3.11.18
• Improves HTTP client performance and reliability
• Enables future Dependabot updates without conflicts
• Maintains full backward compatibility

Fixes #228.

return resp.status == 200
