docs: add link

[Planeshifter]

Description

Link the term probability density function to the [pdf] reference in the opening blockquote of both stats/base/dists/cauchy/pdf/README.md and stats/base/dists/cauchy/logpdf/README.md. Every other non-ctor sibling in the cauchy namespace already wraps its mathematical term in a reference-style link on that line ([cumulative distribution function][cdf], [differential entropy][entropy], [median][median], [mode][mode], [quantile function][quantile-function]). The [pdf]: reference is already defined at the bottom of both files, so the link resolves without further changes. Conformance on this line goes from 6/8 to 8/8; the "natural logarithm of" phrasing in logpdf (from 8d60f41, propagated via #12736) is preserved.

@stdlib/stats/base/dists/cauchy/pdf

Fixed the drift in pdf's README: line 23's opening blockquote referenced "probability density function" as plain text instead of the [probability density function][pdf] link every other non-ctor sibling uses there, even though the [pdf]: reference definition already existed at the bottom of the file. One-line change, brings the cauchy namespace from 6/8 to 8/8 conformance on this pattern. No behavioral, test, or signature changes.

@stdlib/stats/base/dists/cauchy/logpdf

Fixed the logpdf README to link probability density function to the [pdf] reference, matching the pattern used by 6 of the other 7 non-ctor siblings in @stdlib/stats/base/dists/cauchy. The [pdf] anchor was already defined at the bottom of the file, so this is a pure markup fix — no behavioral, test, or signature changes. Namespace conformance on this line goes from 6/8 to 8/8.

Questions

None.

Other

Single conformance percentage: 6/8 non-ctor sibling packages already reference-link the mathematical term in the opening blockquote (75%); pdf and logpdf were the two outliers.

Disclosure

This PR was authored by Claude Code as part of an automated cross-package drift-detection sweep. The routine extracted structural and semantic features from every package in stats/base/dists/cauchy/, computed a per-feature majority pattern, and validated each candidate correction through a structural-review agent (confirmed the linked form is the file's own established convention and the un-linked blockquote is the outlier) and a cross-reference agent (confirmed no test, example, docs/types/*, or generated file depends on the current wording) before any edit. The single correction is a pure Markdown link addition; no behavior, signatures, or tests changed.
