F10: add Chaikin Money Flow, Chaikin Oscillator, Force Index and Ease of Movement

Browse Source 
- Rust core: cmf.rs (Chaikin Money Flow — summed money-flow volume over
  summed volume, bounded to [-1, +1]), chaikin_oscillator.rs (Chaikin
  Oscillator — the MACD of the ADL, EMA(ADL, fast) - EMA(ADL, slow)),
  force_index.rs (Elder's Force Index — EMA of price change scaled by
  volume), ease_of_movement.rs (Arms' Ease of Movement — SMA of distance
  travelled per unit of volume). Each with a full Indicator impl,
  runnable doctest and reference / property / warmup / reset /
  batch==streaming tests.
- Python: PyChaikinMoneyFlow / PyChaikinOscillator / PyForceIndex /
  PyEaseOfMovement PyO3 classes + module registration + .pyi stubs.
- Node: explicit ChaikinMoneyFlowNode / ChaikinOscillatorNode /
  ForceIndexNode / EaseOfMovementNode; index.d.ts and index.js updated.
- WASM: WasmChaikinMoneyFlow / WasmChaikinOscillator / WasmForceIndex /
  WasmEaseOfMovement.
- Wiki: Indicator-ChaikinMoneyFlow/ChaikinOscillator/ForceIndex/
  EaseOfMovement.md plus a new "Oscillators" sub-table in
  Indicators-Overview.md and entries in Home.md.

cargo fmt + clippy (core/wickra/data/wasm/node) clean; 402 core tests,
25 data tests and 57 doctests green.
