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.
