ci(node): add npm release workflow draft (#111)

[midagedev]

Summary

• add Node adapter publish workflow draft (workflow_dispatch + node-v* tag)
• include verify gate (build/typecheck/test) and publish dry-run path
• add Node adapter release gate section in release checklist

Notes

• This PR depends on #107 because the verify job expects workspace package files.
• npm publish only executes when NPM_TOKEN exists and publish trigger is enabled.

Issue

Closes #111
Part of #106
Depends on #107

[midagedev]

Review note: workflow_dispatch currently allows publish=true with an empty version input, which can accidentally publish the development package version. Please enforce explicit version input when manual publish is requested.

Follow-up patch applied:

• manual workflow publish now fails if version input is empty
• added workflow concurrency guard for Node release
• updated release checklist Node gate accordingly
• validated with npm run node:test (pass)
