Python's examples/python/multi_timeframe.py had no Rust or Node sibling.
Add both — the Rust version uses wickra-data's `Resampler` /
`resample_all` (the canonical path; no manual roll-up), the Node version
mirrors the Python one's inline aggregation because wickra-data's
resampler is currently Rust-only.
* examples/rust/src/bin/multi_timeframe.rs — reads the bundled 1m CSV via
`CandleReader`, resamples to 5m / 15m / 1h / 4h / 1d via `resample_all`,
prints last RSI(14), MACD(12,26,9) histogram and ADX(14) per timeframe.
* examples/node/multi_timeframe.js — same outputs from a hand-rolled
bucket aggregator; reuses the new examples/data/ default path.
* examples/README.md gains the new rows.
Run side by side: the Rust and Node summaries are bit-identical at every
timeframe (50000 / 10000 / 3334 / 834 / 209 / 35 bars; same RSI, MACD
histogram and ADX to two decimals) — confirming both the Rust resampler
and the inline Node aggregator produce the same OHLC buckets.
