- #61216: \[Feature\] Let agent choose image generation model per-call

These issues and pull requests concern adding the ability to override the model on a per-turn, per-image-generation, or per-tool-call basis, rather than relying solely on a global model setting. Topics include agent-driven model selection, one-turn overrides, and honoring model fields in image generation calls.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.56`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
