Summary — latest push

Bumps the qmax-code version to 1.20.8 and documents the release of the OpenCode backend alongside per-user, opt-in provider support. The version constant in main.go is updated to match, and the CHANGELOG captures the new features and fixes. The automated review found no issues, aligning with the purely mechanical nature of the version bump and the documentation-only changelog additions.

Important files

File	Score	Notes	Next step
CHANGELOG.md	1/5	Adds the 1.20.8 release entry documenting the new OpenCode backend, per-user provider opt-in, and related fixes.	Verify that the documented commands and feature descriptions match the actual implementation shipped in this version.
main.go	1/5	Updates the Version constant from 1.20.7 to 1.20.8 to reflect the new release.	Ensure the CI build pipeline passes the matching version string via -ldflags to confirm the override works as intended.

Confidence: 5/5

Mechanical version bump and documentation-only changelog update with no behavior-altering code changes.

• Confirm the 1.20.8 changelog entry accurately reflects the scope of changes merged since 1.20.7.
• Verify the OpenCode provider commands and keychain behavior described in the changelog match the shipped implementation.
