feat(ci): publish public packages to both npm and GitHub Packages with dual-scope support

[dongjiang1989]

Which issue(s) this PR fixes:

Summary

• Fix preview-release workflow: explicitly specify public package paths for pkg-pr-new publish to avoid No packages error when internal packages are
  marked private: true
• Add GitHub Packages publishing to the release workflow, publishing under the @iflytek/ scope so packages appear at iflytek/memflywheel/packages
• Refactor scripts/publish-npm.mjs to support dual-registry publishing via --registry flag:
  • npm (default): publishes @iflytekopensource/adapters and @iflytekopensource/hermes
  • GitHub Packages: rewrites scope from @iflytekopensource/ → @iflytek/ (including dependency references) before publishing
• Add .npmrc to .gitignore to prevent accidental commit of temporary auth tokens

Checks

• pnpm run ci
• No old project names, private paths, credentials, or AI-signature footers
• Package metadata still points to iflytek/memflywheel
• Core does not call LLMs directly
• Recall remains full-index, with no embedding/BM25/top-k/vector retrieval

Special notes for reviewers

Publish public packages to both npm and GitHub Packages with dual-scope support

Thanks for adding the dual-registry publish path and the preview-release fix. CI is green, but I found one blocker before approval.

When publishing to GitHub Packages, scripts/publish-npm.mjs rewrites package names and dependency keys from @iflytekopensource/* to @iflytek/*. That makes @iflytek/hermes depend on @iflytek/adapters, but the packaged Hermes runtime still hardcodes @iflytekopensource/adapters in bin/install.mjs, bridge/worker.mjs, and provider/__init__.py. Installing the GitHub-scoped Hermes package would therefore fail to resolve the adapter package.

Minimal fix: when staging GitHub Packages tarballs, also rewrite the runtime adapter import strings in the Hermes package from @iflytekopensource/adapters to @iflytek/adapters, or keep the dependency name aligned with the runtime import. After that I think this is good to approve.

rewrite the runtime adapter

Thanks @OLDyade Good catch.
Change scope rewrite.

Blocker addressed: GitHub Packages scope rewrite now also updates Hermes runtime adapter imports. CI is green.
