chore: update keywords

[Planeshifter]

Description

Follow-up fixes for commits merged to develop between 2026-06-21 13:49 UTC-7 and 2026-06-22 01:52 UTC-7 (56 commits, range e6e7d42b..e0d79b3e).

This pull request:

• Stray add keyword copied from an axpy-style sibling in lib/node_modules/@stdlib/blas/ext/base/sxsy/package.json (c7a7bd4); sxsy implements y = x - y, so replaced with subtract to align with cxsy, gxsy, and zxsy.
• Same add → subtract keyword fix in lib/node_modules/@stdlib/blas/ext/base/dxsy/package.json (096398f); dxsy is the double-precision counterpart of the same operation.
• Stale single keyword in lib/node_modules/@stdlib/blas/ext/base/zxsy/package.json (2a40396), copied verbatim from the single-precision cxsy sibling. Replaced with double to match the double-precision complex semantics; sits alongside the existing complex128/float64 tags.

Audit scope: the 56 first-parent commits to develop in the 24h window (range e6e7d42b..e0d79b3e). Four reviewer agents (two style, two bug) ran in parallel against the union diff and per-package files, cross-checking against sibling packages of similar complexity. Findings were de-duplicated and filtered to high-signal only — objective bugs and unambiguous copy-paste typos in package metadata. Findings that matched pre-existing patterns in sibling packages (e.g. lib/index.js shape in the *-sorted family) were intentionally dropped to avoid expanding scope beyond the diff window. A local report with the full audit trail (validated issues, dropped candidates and rationale, PR URL) lives at ~/drift-reports/commit-review-2026-06-22.md.

Disclosure

This PR was authored by Claude Code running as a scheduled commit-review routine: four reviewer agents audited the last 24h of commits to develop, findings were filtered for high-signal items, and Philipp validated and applied the resulting one-line package.json keyword corrections.
