Close the "multi-timeframe" cell of the cross-language matrix for WASM.
* examples/wasm/multi_timeframe.html — fetches the bundled 1-minute
BTCUSDT CSV (or any 1-minute OHLCV CSV), rolls it up in-page to 5m,
15m, 1h, 4h and 1d buckets, and prints RSI(14), MACD(12,26,9)
histogram and ADX(14) per timeframe via the WebAssembly bindings.
Same inline-bucket aggregation as the Node sibling, same indicator
set as the Python and Rust siblings — the Rust version uses
`wickra-data::Resampler` directly which is currently a Rust-only API.
The render is a single table (one row per timeframe) so the cross-
language outputs sit side-by-side cleanly. The inline module script
syntax-checks cleanly under `node --check`.
