📦 Jules02: Dependency and environment hygiene — hardened config and synced core deps (#603)

* 📦 Jules02: Dependency and environment hygiene — hardened config and synced core deps

- Hardened `TradingConfig` with Pydantic field constraints to match `RISK_LIMITS.md`.
- Synchronized `scikit-learn` (1.7.2) and `structlog` (25.5.0) across all environments.
- Added type stubs for redis, requests, dateutil, and setuptools to CI requirements.
- Updated `test_config_validator.py` to reflect new Pydantic-level enforcement.

- Added type stubs for redis, requests, dateutil, and setuptools to CI requirements.
- Updated `test_config_validator.py` to reflect new Pydantic-level enforcement.
- Fixed CI failures:
    - Added missing `Dict` import in `src/trading/execution_filter.py`.
    - Created `docs/environment_hygiene.md` to satisfy auto-merge documentation policy.
    - Added `python-telegram-bot` to migration safety workflow dependencies.

+### Dependency and Environment Hygiene Improvements
+
+#### Configuration Hardening
+- **Alignment with RISK_LIMITS.md:** Updated `src/core/config.py` with strict Pydantic `Field` constraints (`ge`, `le`) to match enterprise risk standards. Unsafe configurations are now rejected at startup.
+- **Tighter Bounds:**
+    - `max_positions`: reduced maximum from 10 to 5.
+    - `risk_per_trade`: reduced maximum from 5% to 2%.
+    - `max_daily_loss`: reduced maximum from 20% to 6%.
+    - `confidence_threshold`: minimum set to 0.5.
+    - `model_accuracy_floor`: minimum set to 0.5.
+    - `model_win_rate_floor`: minimum set to 0.4.
+
+#### Dependency Synchronization
+- **Consistency:** Unified versions of `scikit-learn==1.7.2` and `structlog==25.5.0` across `requirements.txt`, `requirements-linux.txt`, and `requirements-docker.txt` to eliminate environment drift.
+- **Type Safety:** Added missing type stubs (`types-redis`, `types-requests`, `types-python-dateutil`, `types-setuptools`, `types-PyYAML`) to CI requirements to improve static analysis reliability.
+
+#### Code Quality & Fixes
+- **Fix:** Added missing `Dict` import in `src/trading/execution_filter.py` to resolve CI linting errors.
+- **Validation:** Verified Pydantic enforcement logic and ensured compatibility with existing test suites.
