Manual Review: Release 2.0.5 - Critical Dependency Fixes & Security Hardening

Approving merge for v2.0.5. This PR resolves several critical issues identified during the Python 3.14 adoption testing:

### 🛠️ Key Fixes
1.  **Dependency Resolution (`filelock`)**:
    *   Fixed a logic error where `filelock-lts` (intended for legacy Python) was being forced onto Python 3.14.
    *   Implemented explicit version split: `filelock-lts` for Python < 3.10, upstream `filelock` for Python 3.10+.
    *   Updated `_get_core_dependencies` to respect target interpreter versions.

2.  **Security Hardening (CVE & CodeQL)**:
    *   **Removed `shell=True` usage**: Refactored `_get_latest_version_from_pypi` to use safe `subprocess` lists instead of piping to `grep`. Verification is now handled via Python string manipulation.
    *   **Workflow Permissions**: Restricted `GITHUB_TOKEN` to `contents: read` in `demo-matrix-test.yml` to satisfy CodeQL policy.
    *   **CVE-2025-68480**: Restricted `safety` package installation to Python >= 3.10 to ensure a patched version of `marshmallow` is used.

3.  **Core Stability**:
    *   **Snapshot Restore Crash**: Fixed a `TypeError` in `_safe_restore_from_snapshot` caused by incorrect tuple unpacking of `_run_pip_uninstall` results.
    *   **Knowledge Base Logic**: Fixed a bug in `smart_uninstall` that prematurely wiped global package metadata from Redis while other versions of the package still existed on disk.

### ✅ Validation
*   Python 3.14 adoption successful.
*   Quantum Healing (TensorFlow auto-switch to 3.13) successful.
*   Security scanners (DeepSource/CodeQL) satisfied.
