feat(phase3): Implement Evasion & Resilience Layer + TLS Alignment

- Implement GhostCursorEngine with Bezier curves/Fitts's Law in src/browser/ghost_cursor.py
- Implement EntropyScheduler (Gaussian jitter/phase drift) in src/core/scheduler.py
- Implement MobileProxyRotator (sticky sessions) in src/core/proxy.py
- Update CamoufoxManager to target Chrome 124 for TLS consistency
- Add manual TLS verification script (tests/manual/verify_tls.py)
- Update implementation plan and walkthrough documentation

     -   `select_proxy(session_id)`: Enforces sticky sessions (same session -> same IP).
     -   Cooldown tracking: Prevents reusing IPs too quickly after session termination.
 
+### Remediation: TLS Fingerprint Alignment
+#### [UPDATE] [src/extractor/client.py](file:///home/kasm-user/workspace/FAEA/src/extractor/client.py)
+-   **Objective**: Match `curl_cffi` JA3 fingerprint to Camoufox (Chromium).
+-   **Strategy**:
+    -   Analyze Camoufox's specific Chromium version/build.
+    -   Tune `curl_cffi` `impersonate` parameter (e.g., `chrome120`, `chrome124`, or specific `interaction_args`).
+    -   Verify using `tests/manual/verify_tls.py`.

-- Implement `src/core/proxy.py`.
+- **Status**: PARTIAL.
+- **Verification**: `tests/manual/verify_tls.py` timed out due to network blocks on the test endpoint.
+- **Action Taken**: Updated `CamoufoxManager` to use `Chrome/124` User-Agent and `chrome124` TLS fingerprint target for `CurlClient`. This aligns both tiers to a newer, consistent standard.

+#### Implementation Status
+- **GhostCursorEngine**: Implemented (`src/browser/ghost_cursor.py`).
