release: bump 0.4.5 -> 0.4.6 (#151)
Routine patch release. Ships the **19 TA-Lib parity indicators** (DM components, price transforms, ROC ratio forms, LinReg intercept / TSF, MACDFIX / MACDEXT / SAREXT, Hilbert phasor / DC-phase / trend-mode) added in #148, with the cold-path coverage fix from #150 — indicator count **314**, repo back at 100%.
Version strings bumped `0.4.5 -> 0.4.6` across:
- `Cargo.toml` (workspace + `wickra-core` dep), `Cargo.lock`
- `bindings/python/pyproject.toml`
- `bindings/node/package.json` (+ 6 optional platform deps) and the 6 `npm/<platform>/package.json`
- `bindings/node/package-lock.json`, `examples/node/package-lock.json`
- `CHANGELOG.md` — `[Unreleased]` rolled into `[0.4.6] - 2026-06-03` with refreshed compare links
No code changes. `fmt` / `clippy --workspace -D warnings` green locally.
