chore: align all SDK versions to 1.8.5

Update version numbers to ensure core and SDK versions are in sync:
- core/Cargo.toml: 1.8.4 → 1.8.5
- sdk/node/Cargo.toml: 1.7.2 → 1.8.5
- sdk/python/Cargo.toml: 1.7.2 → 1.8.5
- sdk/node/package-lock.json: 1.7.2 → 1.8.5
- Cargo.lock: update to reflect new versions
