Maintenance release — supply-chain and CI housekeeping only. No library code or
public API changes.
### Security
- Triaged the pyo3 advisories RUSTSEC-2026-0176 / RUSTSEC-2026-0177 as not
affecting Wickra (vulnerable APIs unreachable from the binding; fix blocked
upstream by rust-numpy pinning pyo3 `^0.28`). Recorded in `deny.toml` and
`osv-scanner.toml`.
### Changed
- Java binding: `central-publishing-maven-plugin` 0.5.0 → 0.10.0.
- CI GitHub Actions bumped to latest (checkout, setup-go, setup-java,
codeql-action, taiki-e/install-action).
- Added a Maven ecosystem to Dependabot.
Version bumped across all manifests/lockfiles via `bump_version.py`; Cargo.lock
refreshed. CHANGELOG `[0.8.9]` filled. Tag/publish to follow on explicit GO.
