release: publish npm 0.3.0

[CodeinScrubs]

What changed

Version all 12 aligned @bidilens/* packages to 0.3.0, consume the two reviewed Changesets, regenerate package changelogs and the bundled GitHub Action, align the private demo/root/citation metadata, and update current-release documentation.

Evidence

• Added or updated focused regression tests in the source PR (Add independent alignment plus native Apple and Windows support #24).
• Shared direction corpus remains reproducible across JavaScript, Android, and Apple.
• Source text, selection, copy order, and caller-owned alignment remain logical.
• Ran pnpm run check at 0.3.0 (396/396 tests; build, types, lint, corpus, docs, action bundle green).
• pnpm run test:visual is delegated to this PR's pinned three-browser CI matrix.
• Ran pnpm run npm:release:dry-run -- --version 0.3.0; all 12 tarballs passed and 0.3.0 is unused on npm.
• Consumed the reviewed Changesets for the isolation and alignment changes.

Security and language review

This release does not weaken the existing hidden-bidi-control auditing or source-preservation model. The corpus is technically reviewed and user-provided, not represented as native-speaker certification. Publication remains isolated behind the protected npm-release environment, trusted publishing, provenance, exact version checks, immutable-version rejection, and the exact human confirmation phrase.
