chore: require Node 22.13 for the ZCode CLI

[vitry]

Summary

• Raise the plugin and release baseline from Node 18.18 to Node >=22.13, matching the current ZCode CLI runtime requirement (node:sqlite).
• Update package metadata, shrinkwrap, CI, publish workflow, docs, and integration smoke tests; remove the obsolete bare-addon-resolve pin.
• Keep artifact identity checks safe on Windows Node 22.13: compare the temporary/final files through handle-bound FileHandle.stat() on both sides, avoiding the Node 22.13 Windows lstat/fstat identity mismatch without dropping the TOCTOU check.
• Add Windows compatibility regressions for both artifact reads and writes.

Verification

• Local: npm run check — 380 tests, 378 passed, 0 failed, 2 opt-in E2E skipped.
• CI: Node 22.13 and current LTS on Ubuntu, macOS, and Windows; full check plus packed/native smoke.

This is the follow-up to merged PR #1; it contains only the post-merge Node runtime and Windows compatibility changes.
