Summary

• Align the landing page and current final notes with the published v0.2.0 release, including direct downloads, checksums, and exact-source validation records.
• Distinguish tag commit 2ff90df from measured build commit be39ef9; both have the same source tree. Historical RC and preparation-time records remain unchanged.
• Confirm the current release's 11 asset names, sizes, download URLs, and API SHA-256 digests against the publication record.

Verification and scope

Documentation links and path references were reviewed; the staged whitespace check passed. No tests, builds, or benchmarks were rerun. This is a four-file documentation-only change: no compiler source, media, tag, or release changes are included. The maintainer owns the merge.
