CI's Rust Check runs `cargo clippy --workspace --all-targets -- -D
warnings`; the fmt failure had masked it, so accumulated lints surfaced
once formatting was fixed. Resolve them:
- op-acp / op-ai-skills (this change set): while-let loop, redundant
struct update, and `should_implement_trait` allows on the Option /
infallible token parsers.
- Pre-existing in op-editor-core / op-figma, swept so the workspace
gate is clean: redundant `drop`, `too_many_arguments` allow,
collapsible `if let`, a type alias for a complex tuple, manual
`Iterator::find`, and an `approx_constant` test value.
Lint fixes only — no behaviour change.
