fix(clippy): bring source under -D warnings ahead of CI

Prep for the Forgejo CI gate. Adjustments per module are small
and local:

  - test modules get inner `#![allow(clippy::unwrap_used,
    expect_used, panic)]` so the existing assert.expect()
    test idiom keeps working without rewriting every fixture
  - the dead_code field that downstream consumers may still
    want serialised gets an explicit #[allow(dead_code)]
  - manual char/range comparisons fold to the idiomatic forms
    (`['…']`, `(2..=5).contains(&n)`)
  - one snake_case rename in text-readability-score

Also re-bakes module.wasm so the committed artefact matches
the post-fmt source byte-for-byte.

No behaviour change, no test change. cargo fmt --all -- --check
and cargo clippy --all-targets -- -D warnings now both pass.
