Description

What is the purpose of this pull request?

This pull request:

• adds the missing native C benchmark to math/base/special/cfloor. Every other package in math/base/special that ships a C implementation already has one.

math/base/special/cfloor

• Adds benchmark/c/native/Makefile and benchmark/c/native/benchmark.c. 383 of 384 packages in the namespace (99.7%) have these files, including cceil, cceilf, cfloorf, and cfloorn.
• cfloor already provides src/main.c, lib/native.js, benchmark/benchmark.native.js, and a benchmark task in manifest.json. Its only C benchmark was benchmark/c/benchmark.c, which times libm floor rather than stdlib_base_cfloor.
• The new benchmark mirrors cceil/benchmark/c/native/benchmark.c, with the package name and C function swapped. The Makefile matches cceil and cround apart from the copyright year.

How the drift was found. We extracted structural features (file tree, package.json keys, README section order, manifest.json keys) and semantic features (JSDoc shape, error construction, validation prologue) from all 384 packages in math/base/special. Any feature with at least 75% agreement counted as the majority pattern.

• Every semantic feature in the namespace is uniform. These are pure numeric functions with no validation and no thrown errors, so there was no semantic drift to fix.
• We excluded deviations that reflect real differences between packages:
  • maxn, minn, maxabsn, minabsn, minmaxn, minmaxabsn, and sici have no C implementation at all. Adding one is not a mechanical fix.
  • The kernel-cos, kernel-sin, kernel-tan, and rempio2 READMEs have an extra ### Notes section under ## C APIs. This adds content and doesn't break the pattern.
  • fast is a nested namespace, not a package.
• Native benchmarks also exist outside this namespace: 1639 of 1729 stdlib packages with src/main.c (94.8%) ship a C benchmark.
• Validation: an independent review checked that the native benchmark applies to cfloor and that no tests, examples, or docs depend on its absence. Open PR feat: add assign and strided methods to math/base/special/cfloor #16025 also touches cfloor, but it does not add benchmark/c/native, so the two don't overlap.
• The benchmark was compiled with gcc -std=c99 -O3 against the package sources and run successfully: 1e6 iterations, TAP ok.

Lint PR title failed during npm install, before the title check ran. The @kaciras/deasync install step fails with binding.gyp not found. This PR didn't cause it: every recent lint_pr_title run on develop-based PRs fails the same way, and the diff here touches no dependencies.

I ported the fix from #16328 (pin @kaciras/deasync to 1.0.4) in e5a2aeb. It becomes a no-op once #16328 lands on develop.
