chore: add unsigned keyword to number/uint32/base/add and sub

[Planeshifter]

Description

Adds the "unsigned" keyword to the package.json of @stdlib/number/uint32/base/add and @stdlib/number/uint32/base/sub to bring them in line with the 80% sibling conformance rate within @stdlib/number/uint32/base.

@stdlib/number/uint32/base/add

The keywords array lacked "unsigned", which 8 of 10 packages (80%) in @stdlib/number/uint32/base include. The keyword applies: the package operates on unsigned 32-bit integers via >>>0 coercion and documents operands as {uinteger}.

@stdlib/number/uint32/base/sub

The keywords array lacked "unsigned", diverging from the 80% sibling conformance rate within @stdlib/number/uint32/base. The keyword is semantically correct given the package's use of >>>0 coercion and {uinteger} JSDoc annotations.

Pure package.json metadata change; no runtime behavior, public signature, or test expectation is affected. Precedent for this exact correction shape: #12816 (stats/base/dists/poisson counts keyword) and #12830 (stats/base/dists/negative-binomial keyword alignment).

Disclosure

This PR was drafted by Claude Code as part of a cross-package API drift audit of the @stdlib/number/uint32/base namespace: structural and semantic features were extracted across all 10 members, a single high-signal outlier feature was identified ("unsigned" keyword absent in add and sub despite 8/10 sibling conformance), and three-agent validation (semantic / cross-reference / structural) returned confirmed-drift for both packages before the fix was applied.
