release: bump 0.4.3 -> 0.4.4 (#143)

Release 0.4.4.

Version bump only — no code changes. Ships the 40 TA-Lib candlestick patterns
(parts 2–9, #132–#141, 249 → 289 indicators) plus the candlestick rejection-
guard coverage tests (#142) that landed on `main` since 0.4.3.

Bumped: workspace `Cargo.toml` (+ `wickra-core` dep) and `Cargo.lock`,
`bindings/python/pyproject.toml`, `bindings/node/package.json` (+ 6 platform
`optionalDependencies`), the 6 `bindings/node/npm/*/package.json`, both
`package-lock.json` files, and `CHANGELOG.md` ([Unreleased] → [0.4.4]).
