docs: fix parameter descriptions

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• fixes the C API documentation of stats/base/dists/lognormal/logcdf, which called mu and sigma the "mean" and "standard deviation". For a lognormal distribution these are the location and scale parameters.

@stdlib/stats/base/dists/lognormal/logcdf

The README C APIs section, the src/main.c doc comment, and the logcdf.h header described mu and sigma as "mean" and "standard deviation", wording carried over from normal/logcdf. They now say "location parameter" and "scale parameter". This matches the package's own JavaScript docs and the C docs of 12 of the 13 native packages in the namespace (92%). The change is to comments and docs only.

Namespace summary. This fix came from comparing all 14 packages in stats/base/dists/lognormal, using a 75% agreement threshold.

• Features analyzed: file tree, package.json keys, manifest.json keys, README sections, native boilerplate, public signature, validation prologue, error construction, JSDoc shape, dependencies, and C API docs.
• Features with a clear majority (≥75%): most of them.
• Features without one (excluded): public signature, since arity depends on the function type, and the JSDoc @returns type (number 7, NonNegativeNumber 6, Probability 1).

Validation. Each package's features were extracted from its files, plus a per-package read of the source. Each outlier was then reviewed by three agents (semantic, cross-reference, structural). These deviations were reviewed and left as they are:

• logcdf has no sigma <= 0 NaN guard and documents sigma as {NonNegativeNumber}. This is intentional: sigma = 0 is a documented degenerate case, and the tests cover it.
• stdev has no validation prologue. It inherits validation from variance.
• ctor lacks the native addon and C APIs section. It is a JS-only class.
• logcdf uses R fixtures instead of Julia fixtures. These are valid reference values from a different tool.
• logcdf has no docs/img equation SVG. Adding one is not a mechanical fix.
