[AZ-178] Implement streaming video detection endpoint

- Added `/detect/video` endpoint for true streaming video detection, allowing inference to start as upload bytes arrive.
- Introduced `run_detect_video_stream` method in the inference module to handle video processing from a file-like object.
- Updated media hashing to include a new function for computing hashes directly from files with minimal I/O.
- Enhanced documentation to reflect changes in video processing and API behavior.

+## When to generate a local `run-tests.sh`
+
+A local shell script is needed **only** for hardware-dependent projects that require real hardware (GPU, CoreML, TPU, sensors, etc.) to exercise the actual code paths. If the Hardware-Dependency Assessment (Phase 4 prerequisite) determined **local** or **both** execution, generate this script.
+
+For all other projects, **use Docker** (`docker-compose.test.yml` / `Dockerfile.test`). Docker is the default — it provides reproducibility, isolation, and CI parity. Do not generate a local `run-tests.sh` when Docker is sufficient.

 ## Key Requirements
 
+- **Docker is the default**: only generate a local `run-tests.sh` for hardware-dependent projects. Otherwise use `docker-compose.test.yml`.
+- **Always install dependencies first**: the script must install all project and test dependencies before building or running tests. A fresh clone or CI runner may have nothing installed. Missing a single dependency causes collection errors that abort the entire test run.
 - Both scripts must be idempotent (safe to run multiple times)
 - Both scripts must work in CI (no interactive prompts, no GUI)
 - Use `trap cleanup EXIT` to ensure teardown even on failure
