- Add RequestSizeLimitMiddleware that checks Content-Length header
before request body is read: non-multipart requests capped at
MAX_REQUEST_BODY_SIZE (default 1 MB), multipart uploads capped at
MAX_UPLOAD_SIZE (default 1 GB). Returns HTTP 413 on violation.
- Register middleware in app/main.py
- Add max_request_body_size setting to app/config.py
- Fix ui_upload in files.py to check Content-Length early and read
in 64 KB chunks (bounded memory usage), removing the post-write
os.path.getsize check
- Document MAX_REQUEST_BODY_SIZE in .env.demo and ConfigurationGuide.md
- Mark SECURITY_AUDIT.md item #4 as resolved
- Add 9 tests in test_request_size_limit.py
- Update test_upload_file_too_large to use patch.object instead of
the now-unused os.path.getsize mock
Closes#173
