Summary

Prepare the stable duroxide npm patch release 0.2.2, including the upgrade to duroxide-pg 0.1.37.

• Bump duroxide-pg from 0.1.36 to 0.1.37; retain core duroxide at 0.1.32.
• Set the root npm package, all five platform packages, optional dependency versions, and lockfile metadata to 0.2.2.
• Finalize the 0.2.2 changelog dated 2026-10-21, leaving an empty Unreleased section.
• Update dependency version examples in the architecture documentation and contributor instructions.

Validation

• Native debug build passed with duroxide-pg 0.1.37 and duroxide 0.1.32.
• Release version alignment and changelog assertions passed.
• npm pack --dry-run --ignore-scripts --json passed for duroxide@0.2.2.
• git diff --check passed.
• Full test suite and cross-platform builds were not run locally; these are covered by PR CI.

Existing tooling limitation: npm ci fails because the lockfile lacks platform optional-package entries. Build dependencies were installed without changing the lockfile dependency graph.

Publishing
