feat: add Java→Python migration plan with 9 self-contained phase files

Converts Spring Boot 4.0.3 ARMA Server Web GUI to FastAPI/Python. Each phase file is fully self-contained: lists Java source files to read, output files to create, implementation patterns, REST endpoint contracts, and a completion checklist. A future agent can execute any single phase without rescanning the Java project. Phases: - 01: Foundation — SQLAlchemy models, Alembic, settings, base schemas - 02: Auth & Users — JWT middleware, RBAC, user CRUD - 03: CFG parser + server process — server.cfg round-trip, start/stop - 04: Server settings — general/network/logging/security/difficulty - 05: Mod management — mod CRUD, presets, settings, WebSocket progress - 06: Steam integration — SteamCMD queue, Workshop API, python-a2s - 07: Missions, CDLC, Discord, APScheduler jobs - 08: Middleware & polish — global exception handler, SPA redirect, structlog - 09: Testing — pytest-asyncio, respx, 80% coverage target

+# Phase 9 — Testing
+
+**Status**: PENDING
+**Depends on**: Phases 1–8 all complete (`from src.main import app` must import without error)
+**Next phase**: None — final phase
+
+---
+
+## Goal
+
+Achieve ≥ 80 % line coverage across `src/`. Every public contract tested with real SQLite-in-memory DB and
+`httpx.AsyncClient` over ASGI transport. No mocking of internal service classes. Steam API HTTP calls mocked
+with `respx`.
+
+---
+
+## Tools & Libraries
+
+| Package | Purpose |
+|---------|---------|
+| `pytest` | Test runner |
+| `pytest-asyncio` | `asyncio_mode = "auto"` for async fixtures |
+| `pytest-cov` | Coverage measurement |
+| `httpx` | ASGI test client |
+| `respx` | Mock httpx HTTP calls (Steam Web API) |
+| `aiosqlite` | Async SQLite driver for in-memory test DB |
+| `sqlalchemy[asyncio]` | Same ORM as production |
+| `bcrypt` | Password hashing (same as production) |
+| `python-jose` | JWT signing for test auth tokens |
+
+Install:
+```
+pip install pytest pytest-asyncio pytest-cov httpx respx aiosqlite python-jose
+```
+
+---
+
+## pytest.ini / pyproject.toml
+
+```ini
+[pytest]
+asyncio_mode = auto
+testpaths = tests
+```
+
+```
+pytest --cov=src --cov-report=term-missing --cov-fail-under=80

+## Completion Checklist
+
+- [ ] `pytest` runs without import errors on a clean checkout (after `pip install -r requirements.txt`)
+- [ ] `tests/unit/test_cfg_parser.py` — all 6 round-trip tests pass
+- [ ] `tests/unit/test_permissions.py` — 37-value enum check passes
+- [ ] `tests/integration/test_auth.py` — login / 401 / token tests pass
+- [ ] `tests/integration/test_mods.py` — collection shape and enabled POST pass
+- [ ] `tests/integration/test_workshop.py` — `respx` mock returns paginated mods
+- [ ] `tests/integration/test_error_handler.py` — 500 returns `{"code":"SERVER_ERROR",...}`
+- [ ] Coverage: `pytest --cov=src --cov-fail-under=80` exits 0
+- [ ] No test imports production `.env` or writes to the real database
+- [ ] `asyncio_mode = "auto"` in `pytest.ini` (no manual `@pytest.mark.asyncio` needed)
+

+
+## Coverage Exclusions
+
+Add to `.coveragerc` or `pyproject.toml` to avoid penalising untestable glue:
+
+```ini
+[coverage:run]
+omit =
+    src/main.py           # ASGI wiring — tested implicitly by client fixture
+    src/alembic/*
+    tests/*
+```
+
+---
+
+## Contract Satisfied
+
+All 17 routers, 3 middleware layers, global exception handler, WebSocket endpoint, and two actuator endpoints are exercised through the `AsyncClient(transport=ASGITransport(app=app))` fixture. The test suite constitutes a full regression suite equivalent to the Java integration tests.
