feat(bindings): expose name() on every indicator in all 10 languages (#308 )

* feat(bindings): expose name() on every indicator in Node, WASM, and Python

Surface the core Indicator::name() / BarBuilder::name() accessor through the
three native bindings so every indicator reports its canonical name at runtime,
matching the existing reset/isReady/warmupPeriod surface.

- Node (napi): name(): string on all 514 classes (regenerated index.d.ts)
- WASM (wasm-bindgen): name(): string on all 514 classes
- Python (pyo3): name() -> str on all classes

* feat(bindings): expose name() across the C ABI and C/C++/Go/C#/Java/R

Regenerate the C ABI and the four generated language bindings from the updated
ScriptHelpers generators so every indicator and bar builder reports its
canonical name at runtime, completing name() coverage across all 10 languages.

- C ABI (bindings/c): wickra_<ind>_name() -> *const c_char for all 514, cached
  in a per-function OnceLock<CString> with ind.name() as the source of truth;
  cbindgen header regenerated and vendored into bindings/go/include.
- Go: Name() string; C#: string Name(); Java: String name(); R: name() S3
  generic over the wk_<ind>_name C glue (methods.R + NAMESPACE).

The Java regeneration also restores two fixes that had drifted out of the
generator (bool* arrays via boolSegment; uint8_t ctor args cast to byte) and C#
re-emits '#nullable enable'; these are no-op vs the previous committed output
apart from the new name() accessors.

* test(golden): pin canonical name() across all 10 language bindings

Add a cross-language name() consistency check: every indicator must report the
exact core Indicator::name() (which can differ from the registered class name,
e.g. ChaikinMoneyFlow -> "CMF", Donchian -> "DonchianChannels"). The 514 core
names are committed as testdata/golden/names.json (keyed by Rust canonical) and
asserted by each binding's golden replay, which already reconstructs the whole
catalogue:

- node / wasm: assert against names.json in the existing golden test
- python: new test_golden_names.py over the shared node manifest
- go / csharp / java / c+c++ / r: the golden-test generators load names.json and
  emit a name assertion per indicator (regenerated test artifacts committed)

All 10 bindings return identical names by construction (each delegates to core),
so this pins that contract and guards against a future binding breaking the
passthrough.

* docs(changelog): record name() across all 10 bindings under Unreleased

* fix(r): restore bool* flag marshalling in the regenerated C glue

The name() regeneration had reverted the cross-section bool fix: the R glue
emitted (bool *)REAL(x) for const bool* inputs, reinterpreting 8-byte doubles as
1-byte bools so every flag read as false (PercentAboveMa, NewHighsNewLows,
HighLowIndex, BullishPercentIndex returned 0 instead of the breadth value). The
wk_bool_vec() helper is restored in the generator and the glue routes bool arrays
through it again.

Add the R binding over the C ABI hub (#230 )

Adds an R binding (`bindings/r`) over the C ABI hub — the third language stecker after C# and Go, reaching the hub through R's native `.Call` interface (not extendr).

## What's here
- **`bindings/r`** — an R package exposing all 514 indicators as constructors that return a `wickra_indicator` object with generic `update`/`batch`/`reset` methods. The C glue (`src/wickra.c`) and R wrappers (`R/indicators.R`) are generated from `bindings/c/include/wickra.h` (same archetype taxonomy as the C#/Go generators: scalar/batch, multi-output, bars, profile, profile-values, array-input). The opaque handle is an R external pointer freed by a registered finalizer; multi-output returns a named vector (`NA` at warmup), bars a matrix, profiles a list.
- **`examples/r`** — the full example suite mirroring C/C#/Go: streaming, backtest, multi_timeframe, parallel_assets (`mclapply`), three strategies, and `fetch_btcusdt`/`live_binance`.
- **CI** — an `r` job builds the C ABI library, installs the package, runs the `testthat` suite and the offline examples on Linux, macOS and Windows (`R CMD check` is clean: 0 warnings, 0 notes).
- **Docs** — R added to the README languages table, project layout, building/testing, CONTRIBUTING binding table + regenerate note, ARCHITECTURE, examples index, issue/PR templates, the About-description template, and the other binding READMEs.

## Linking / distribution
The package compiles a thin `.Call` glue layer against the prebuilt C ABI library (header via `WICKRA_INCLUDE_DIR`, library via `WICKRA_LIB_DIR`). On Windows the package's own `wickra.dll` would collide with the C ABI's `wickra.dll`, so `configure.win` stages a renamed copy (`wickra_abi.dll`) and builds an import library referencing it; `install.libs.R` bundles the DLL and `.onLoad` puts it on the load path. On Linux/macOS the rpath locates the shared library. No `release.yml` change — R is distributed via r-universe / source install (gated).

No Rust crate or `Cargo.toml` change — the R package is standalone and additive.
