Summary

• Pair the Genkit docs with the now-published genkit_llamadart 3.9.0 and llamadart 0.19.7, as #1823 did for 3.8.0. Listed in #1950.
• website/docs/integrations/genkit.md: prose, dart pub add snippet, GGUF Apple companion 0.19.7. choosing-an-api.md: Genkit row. packages/genkit_llamadart/README.md: install floor now states llamadart 0.19.7 or newer 0.19.x (3.9.0 requires ^0.19.7).

Production-readiness scope

• User-facing scope: current docs install the published 3.9.0 / 0.19.7 pairing.
• Supported platforms/paths: docs only; versioned docs snapshots and released changelog sections unchanged.
• Unsupported or intentionally unavailable paths: unchanged.
• Out of scope / follow-ups: None.

Completeness checklist

• Declared scope is fully implemented, or explicitly reduced above.
• Unsupported platform/option combinations fail loudly with actionable diagnostics or are clearly documented as unavailable. N/A: docs pins only.
• Public API docs, README/website docs, examples, support matrices, and changelog entries are updated where relevant. No changelog entry, as in Pair the Genkit docs with genkit_llamadart 3.8.0 and llamadart 0.19.0 #1823.
• Regression coverage covers the original issue plus key negative/version-skew paths where relevant. N/A: docs only.
• Public capability changes update the validation coverage registry with a pack or a reasoned, issue-linked exemption; inventory checks pass (or N/A with scope). N/A: no capability change.
• Security/privacy review completed: version strings only.
• Follow-up work that is useful but not required for this PR is tracked in GitHub Issues, or explicitly marked "None" above. None.
