유창욱 8958dd1b83 chore: pin runtime dependencies for offline air-gapped install
Add requirements.txt (numpy/opencv-python-headless/pillow — the only
third-party runtime imports) and requirements-dev.txt, plus an offline
install runbook. Ignore .coverage and wheelhouse/.

# Offline (air-gapped / 폐쇄망) install
The deployment target has **no internet**. All Python dependencies must be
carried across the air gap as pre-downloaded wheels. The build/staging machine
(which has internet) does the downloading; the target only installs.
## Prerequisites
- Same OS + CPU architecture + **Python 3.13** on build and target machines
(wheels are platform- and version-specific).
- The repository itself transferred to the target.
## 1. On the build machine (has internet)
```bash
# Runtime only:
pip download -r requirements.txt -d wheelhouse/
# Or runtime + test tooling:
pip download -r requirements-dev.txt -d wheelhouse/
```
This fills `wheelhouse/` with every wheel (including transitive deps).
## 2. Transfer
Copy both the repository and the `wheelhouse/` directory to the target via the
approved air-gap transfer process (e.g. removable media).
## 3. On the target machine (no internet)
```bash
python -m venv .venv
. .venv/bin/activate # Windows: .venv\Scripts\activate
pip install --no-index --find-links wheelhouse/ -r requirements.txt
```
`--no-index` guarantees pip never reaches out to the internet; `--find-links`
points it at the local wheelhouse.
## 4. Verify offline
```bash
# Confirm no network access is attempted and imports resolve:
python -c "import numpy, cv2, PIL; print('deps ok')"
python -m pytest -q # if test deps were installed
```
## Notes
- The operator GUI (`web/operator-gui/`) is fully self-contained: all
scripts/styles are local and the Pretendard font is bundled
(`assets/fonts/PretendardVariable.woff2`). No CDN fetch at runtime.
- External **search** APIs (Google / Naver / Cloud Vision) are an allowed
runtime exception and require outbound access to those providers ONLY. They
are optional; missing credentials disable the provider (see the startup
provider-readiness log).
- `COPYRIGHTER_AUTH_TOKEN` should be set in `.env` for any multi-operator or
networked deployment so the data routes require a shared token.
