fix(release): synchronize 3.0.3 public facts

[wybaby168]

Summary

• Synchronize the published v3.0.3 package, matrix, site, demo, and documentation facts.
• Add a source-derived public gate so release metadata cannot drift from the immutable package evidence.

Related issue

N/A: a production metadata audit found stale 3.0.0 facts after the immutable 3.0.3 package release.

Change classification

• User-visible UI or rendering change
• Non-visual change
• File-format or renderer behavior
• Public API, package, Worker, WASM, or deployment-path change

Verification

Check	Result
pnpm verify:public-release-facts	Passed
pnpm verify:github-governance	Passed
pnpm site:build	Passed
pnpm docs:build	Passed

Sample / Fixture Evidence

• N/A: no renderer or file-format behavior changed.

Visual Evidence

• N/A: this synchronizes release metadata and adds a source-derived consistency gate; it does not alter public UI layout or rendering behavior.

Risk and compatibility

• Affected packages/formats: public site, demo, documentation, and release metadata only; npm tarballs and renderer behavior remain immutable.
• Compatibility or migration risk: consumers retain v3.0.3 package bytes and existing Vue 2 and Full contracts.
• Rollback: revert this public facts commit and redeploy the prior static site build; no package unpublish or tag rewrite is involved.

Checklist

• I added or updated focused automated coverage, or explained why it is not needed.
• I updated user-facing documentation or release notes when behavior or API changed, or marked them not applicable.
• I verified offline/private-deployment paths when changing Worker, WASM, fonts, vendor assets, or URLs.
• I did not commit secrets, customer files, private samples, generated caches, or unrelated changes.
