docs: add asm type annotation

[Planeshifter]

Description

This pull request adds the // asm type annotation trailing comment to the |0 coercion in constants/float32/num-significand-bits. It was the sole package in the namespace applying the asm.js |0 idiom without the annotation carried by 90% (18/20) of its |0-idiom siblings.

constants/float32/num-significand-bits

The |0 coercion on the exported integer32 constant lacked the // asm type annotation comment used across the namespace's integer constants. This aligns the single outlier with the established convention. The change is comment-only; the exported value (23), the integer32 type, and the tests are unchanged.

The correction was surfaced by structural and semantic feature extraction across the 68-member constants/float32 namespace, then cross-referenced against the parallel constants/float64 namespace to separate intentional per-constant curation (e.g. @see and keyword differences, which mirror float64) from genuine drift. The missing annotation was the only high-signal, mechanical, non-behavioral correction to survive filtering, and it is not mirrored in float64 (which has no num-significand-bits package).

Disclosure

This PR was authored by Claude Code running an automated cross-package drift-detection routine. The routine extracted structural and semantic features across the namespace, computed the majority convention per feature, cross-referenced the constants/float64 sibling namespace to reject intentional deviations, and applied the single surviving one-line comment correction. The change was reviewed against sibling-package conventions before submission.
