Merge pull request 'feat(gifsmith): point the agent at the render harness and state the quality bar' (#26) from feat/gifsmith-staging-prompt into main

The gif pack now bundles a render harness rather than a bare encode helper, so
the system prompt names it. It also states what the agent is actually aiming
for: measurement against production runs showed the common failure is not a
broken render but a technically-correct one that reads badly — subject drawn too
small to recognise, action narrated in a caption instead of animated. Full
findings in mort docs/audits/2026-07-24-gifsmith-quality.md.
