feat(indicators): B3 Trend & Directional batch (413 -> 420) (#181)
Adds the **B3 — Trend & Directional** batch: seven new indicators, taking the catalog from 413 to 420 (Trend & Directional family). | Indicator | Input → Output | Summary | |-----------|----------------|---------| | `Qstick` | candle → f64 | Chande's SMA of the candle body (close − open) | | `TtmTrend` | candle → f64 (±1) | John Carter close-vs-median-SMA trend filter | | `TrendStrengthIndex` | f64 → f64 | signed r² of an OLS regression of price vs time | | `PolarizedFractalEfficiency` | f64 → f64 | Hannula directional trend efficiency | | `WavePm` | f64 → f64 | Kase variance-normalised peak-momentum statistic (reconstruction) | | `GatorOscillator` | candle → struct | Bill Williams Alligator convergence/divergence histogram | | `KasePermissionStochastic` | candle → struct | double-smoothed stochastic permission filter | Note: the roadmap's "Directional Indicator +DI/−DI" item is already covered by the existing standalone `PlusDi` / `MinusDi` / `Dx`, so it is intentionally not re-added. All touchpoints wired: core (every-branch unit tests), Python/Node/WASM bindings, fuzz drivers, Python test registries + reference tests, Node factories, README/CHANGELOG counters. Local verify: `cargo test -p wickra-core` (lib 3389 + doc 378), `cargo clippy --workspace --all-targets --all-features -- -D warnings`, node build + 495 tests, maturin + 815 pytest, counter 420 == 420.
