F-Abschluss: wire the Python package, refresh docs and extend the test suites

Finalises the F1-F12 indicator expansion (25 -> 63 indicators).

- Python `wickra/__init__.py`: import and re-export all 63 indicators,
  grouped by family, with a matching `__all__`. The package previously
  exposed only the original 25 even though the compiled module and the
  `.pyi` stubs already carried the rest.
- Docs: `Home.md` and `README.md` indicator counts and family tables
  updated to 63; `Indicators-Overview.md` already restructured per family
  in F10-F12; `Warmup-Periods.md` gains all 38 new indicators across the
  single- and multi-output tables (and the stale two-arg `Psar::new`
  example is corrected to three args); `CHANGELOG.md` `[Unreleased]` lists
  every new indicator by family.
- Tests: `bindings/node/__tests__/indicators.test.js` covers all 63
  indicators (streaming==batch plus four new reference-value checks),
  80/80 green; new `bindings/python/tests/test_new_indicators.py` covers
  the 38 additions (streaming==batch, shapes, reference values,
  lifecycle), Python suite 105/105 green.
- `bindings/node/index.js` regenerated by `napi build`.

cargo fmt + clippy (core/wickra/data/wasm/node) clean; 454 core tests,
25 data tests, 66 doctests, 80 Node tests and 105 Python tests green;
`cargo check -p wickra-wasm --tests` green.

 ## [Unreleased]
 
 ### Added
+- 38 new technical indicators, taking the library from 25 to 63. Each is
+  implemented once in the Rust core and wired through the Python, Node and
+  WASM bindings, with reference-value tests and a dedicated wiki page:
+  - Trend: `Smma`, `Trima`, `Zlema`, `T3`, `Vwma`.
+  - Momentum: `Mom`, `Cmo`, `Tsi`, `Pmo`, `StochRsi`, `UltimateOscillator`,
+    `Ppo`, `Dpo`, `Coppock`, `AroonOscillator`, `Vortex`, `MassIndex`.
+  - Volatility: `Natr`, `StdDev`, `UlcerIndex`, `HistoricalVolatility`,
+    `BollingerBandwidth`, `PercentB`, `SuperTrend`, `ChandelierExit`,
+    `ChandeKrollStop`, `AtrTrailingStop`.
+  - Volume: `Adl`, `VolumePriceTrend`, `ChaikinMoneyFlow`,
+    `ChaikinOscillator`, `ForceIndex`, `EaseOfMovement`.
+  - Statistics: `TypicalPrice`, `MedianPrice`, `WeightedClose`,
+    `LinearRegression`, `LinRegSlope`.
 - `TickAggregator::with_gap_fill` — opt-in mode that emits a flat placeholder
   candle for every empty bucket between two ticks, keeping the candle series
   evenly spaced for downstream indicators.
