Squeeze-setup detector — directional flow z-scores correlated with momentum.

Detects bullish/bearish squeeze setups by correlating directional flow z-scores
with momentum acceleration and dealer-gamma posture. Standalone event detector,
not part of the MSI composite.

**Logic highlights** (`src/signals/advanced/squeeze_setup.py`):
- Bullish: `call_flow_z × tanh_scaled(momentum) × momentum_strength × 1.2 (if accelerating)
  × (1.0 if above flip else 0.6) × (1.0 if net_gex < 0 else 0.5)`.
- Bearish: symmetric using `put_flow_z`.
- **Triggered when `|score| ≥ 25` (clamped 0.25).**
- Dead-VIX regime (`vix_level < 15`) attenuates strength ~50%.

**Params:** `symbol` (default `SPY`). Returns 404 when no data exists.

**Returns:**
```json
{
  "score": 38.0, "clamped_score": 0.38, "direction": "bullish",
  "triggered": true,
  "signal": "bullish_squeeze",
  "call_flow_delta": 125000.0, "put_flow_delta": -45000.0,
  "call_flow_z": 2.1, "put_flow_z": -0.8,
  "momentum_z": 1.4,
  "vix_regime": "normal",
  "context_values": {"...momentum_5bar, momentum_10bar, accel_up, accel_dn, net_gex, gamma_flip, flow_norm_used..."},
  "score_history": [{"score": 38.0, "timestamp": "..."}, "...up to 90"]
}
```

- `score` — [-100, +100].
- `signal` — `"bullish_squeeze"` | `"bearish_squeeze"` | `"none"`.
- `triggered` — `true` when `|score| ≥ 25`.
- `call_flow_z` / `put_flow_z` — z-scores; typically [-5, +5].
- `vix_regime` — `"dead"` | `"normal"` | `"elevated"` | `"panic"` | `"unknown"`.

**Trader interpretation:**
- `signal == "bullish_squeeze"` + `accel_up == true` + price above gamma flip
  + `net_gex < 0` → classic short-gamma squeeze; long call spreads.
- `vix_regime == "dead"` → cut conviction; dead-vol regimes lack squeeze fuel.
- `momentum_z` vs flow z-scores divergence: flow without price = early signal;
  price without flow = exhausted move.

**Page design.** Signal pill (bullish/bearish/none) with `triggered` as a bright dot.
Paired bar showing `call_flow_z` and `put_flow_z`. VIX regime chip (color-coded).
