Behavior-preserving cleanup of AI-generated code smells in 5 files authored/moved by this PR:
- src/hooks/model-fallback/fallback-state-controller.ts (-47/+47 net reorganization, redundant defensiveness removed)
- src/shared/model-string-parser.ts (-4 LOC obvious-comment cleanup)
- src/shared/ripgrep-cli.ts (-13 LOC obvious comments + redundant defensive checks)
- src/tools/delegate-task/tool-description.ts (-6 LOC)
- src/tools/look-at/look-at-input-preparer.ts (-6 LOC)
Targets: obvious comments that restate code, over-defensive null checks on guaranteed values, redundant existence checks. No public API signatures changed, no type hints removed, no new abstractions introduced. Full test suite still passes.
Extract input preparation and image conversion handling into look-at-input-preparer.ts.
Extract prompt construction and multimodal session execution into look-at-prompt.ts and look-at-session-runner.ts while keeping createLookAt stable.
