docs: fix stale factory example return values in @stdlib/stats/base/dists/lognormal/logpdf

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request corrects two stale return values in the @module documentation example of @stdlib/stats/base/dists/lognormal/logpdf.

• logpdf.factory( 4.0, 2.0 ) evaluates to ~-4.275 at x = 10 and ~-3.672 at x = 2. lib/index.js documented ~-4.269 and ~-3.689. The correct values are already present in the package's own lib/factory.js, README.md, and docs/repl.txt, so lib/index.js was the lone stale copy. The fix also restores the cross-package invariant that a member's lib/index.js factory example matches its lib/factory.js output, which holds for the namespace's four other factory-bearing members (cdf, pdf, quantile, logcdf): conformance goes from 4/5 (80%) to 5/5 (100%). Comment-only change; no observable behavior or test expectations are affected.

The discrepancy was found via a cross-package documentation-consistency check across the stats/base/dists/lognormal namespace. The corrected values were recomputed directly (node -e "require('.../logpdf/lib/factory.js')(4,2)(10)" → -4.2748…, (2) → -3.6721…). No other drift in the namespace survived filtering; all remaining deviations (e.g. ctor lacking C bindings, logcdf supporting the degenerate sigma = 0 case) are intentional and were deliberately excluded.

This PR was authored by Claude Code running an automated cross-package documentation-consistency check. The stale values were identified by comparing the @module example in lib/index.js against the package's lib/factory.js, README.md, and docs/repl.txt, and the corrected values were verified by recomputing the factory output with Node.js.
