Add stable link to latest release notes using Hugo aliases

[Copilot]

Release notes are versioned by date (e.g., releasenotes_2025_12.md), requiring users to know the exact filename. This adds a stable /releases/release-notes/latest/ URL that always redirects to the most recent release.

Changes

• Added alias to latest release note: releasenotes_2025_12.md now includes aliases = ["/releases/release-notes/latest/"] in front matter, generating an HTML meta refresh redirect
• Added visible link on Release Notes page: A prominent "What's New - Latest Release" link now appears on the Release Notes index page (content/releases/release-notes/_index.md), providing easy access to the latest release
• Documented maintenance: README now includes instructions to move the alias when publishing new releases
• Added inline documentation: Comment in _index.md explains the redirect mechanism

Maintenance

When publishing a new release:

1. Add aliases = ["/releases/release-notes/latest/"] to the new release note
2. Remove the alias from the previous release note

Hugo generates a redirect at build time. No server-side configuration or additional dependencies required.

Added a prominent link to the latest release notes on the Release Notes page (commit a599ca4).

The link uses a relative path (latest/) which will automatically redirect to the current latest release notes using Hugo's alias feature.
