kingchenc 4f81222aed Deepen Momentum Oscillators family with ten additions (#179 )

Deepens the **Momentum Oscillators** family with ten widely-used oscillators
(403 → 413 indicators), the second batch of Part B (family deepening).

| Indicator | Binding | Input → Output |
|-----------|---------|----------------|
| `DisparityIndex` | `DisparityIndex` | scalar → scalar |
| `FisherRsi` | `FisherRSI` | scalar → scalar |
| `Rmi` | `RMI` | scalar (period, momentum) → scalar |
| `DerivativeOscillator` | `DerivativeOscillator` | scalar (4 periods) → scalar |
| `Rsx` | `RSX` | scalar → scalar |
| `DynamicMomentumIndex` | `DynamicMomentumIndex` | scalar → scalar |
| `IntradayMomentumIndex` | `IMI` | candle (open+close) → scalar |
| `StochasticCci` | `StochasticCCI` | candle → scalar |
| `ElderRay` | `ElderRay` | candle → struct (bull/bear) |
| `Qqe` | `QQE` | scalar → struct (rsi_ma/trailing) |

LSMA was dropped from the planned set: it already ships as `LinearRegression`.

The single-period scalars use generated macro bindings; `Rmi` /
`DerivativeOscillator` use hand node/python bindings with the typed wasm macro;
`ElderRay`/`Qqe` use custom struct bindings; `IntradayMomentumIndex` uses custom
candle bindings carrying the open. Full coverage: core modules with per-branch
unit tests, mod/lib catalogue, FAMILIES + assert, README + docs counters,
CHANGELOG, all three bindings (regenerated `index.d.ts`/`index.js`), fuzz
drivers, and the python/node test registries.

Local verification: `cargo test -p wickra-core` (lib 3335 + doc 371),
`cargo clippy --workspace --all-targets --all-features -D warnings` clean,
node `npm run build && npm test` (488), python `pytest` (802).

Documentation

Wickra's full documentation lives at docs.wickra.org.

That includes:

Quickstarts for Rust, Python, Node, and WASM.
A per-indicator deep dive for every one of the 413 indicators across the sixteen families (Moving Averages, Momentum Oscillators, Trend & Directional, Price Oscillators, Volatility & Bands, Bands & Channels, Trailing Stops, Volume, Price Statistics, Ehlers / Cycle DSP, Pivots & S/R, DeMark, Ichimoku & Charts, Candlestick Patterns, Market Profile, Risk / Performance) — see the indicators overview.
Reference pages: warmup periods, streaming vs batch, indicator chaining, and the data layer.
Guides: Cookbook, TA-Lib migration, FAQ.
