fix(release): tolerate npm registry propagation

[kauandotnet]

Summary

• wait up to five minutes for npm metadata and tarball propagation
• resume safely when a prior attempt already published a package
• write Changesets publish events so release tags and release outputs remain available

Verification

• node --check scripts/publish.mjs
• pnpm exec prettier --check scripts/publish.mjs
• pnpm exec oxlint scripts/publish.mjs
• git diff --check
