toolchain rule: Rust 1.81 + clippy, integer/ternary only

Pin channel 1.81.0 with clippy+rustfmt; rust-version = "1.81"; replace
rust-1.97-independent-verification.yml with rust-1.81-clippy-verification.yml
(clippy --all-targets -D warnings, hard fail on any f32/f64, tests, receipt).

Re-run on real rustc 1.81.0 (eeb90cda1) before landing: clippy -D warnings
clean, zero float types, all tests pass. The run records in docs/ now read
1.81 because the runs were actually repeated on 1.81 - not because the lines
were edited.

Lint fix needed to reach clippy-clean on 1.81 (behaviour-preserving):
op_ref: drop the needless & on the left operand of a str/String comparison (src/lib.rs:304). 19/19 tests.
