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.
