refactor: use main as require alias in stats/base/dists/frechet

[Planeshifter]

Description

Normalizes the require( './main.js' ) alias in three lib/index.js files under stats/base/dists/frechet from the package-name form (e.g. var mean = ...) to the canonical var main = ... form, with matching module.exports updates. Internal-only rename: the exported value is unchanged.

Namespace summary

• Target namespace: @stdlib/stats/base/dists/frechet
• Members: 14, all hand-written (no autogenerated packages)
• Features analyzed: file tree, package.json shape, README sections, lib/ file set, lib/index.js require-alias variable, error-construction shape
• Features with clear majority (≥75%): lib/index.js require-alias variable (11/14 = 78.6% use var main)
• Features without clear majority: none material; native-binding presence (12/14) was excluded because adding a native binding is not a mechanical fix and the absences (ctor, pdf) are intentional (constructor; trivial exp(logpdf(...)) wrapper)

Per outlier package

stats/base/dists/frechet/mean

Renames the local alias in lib/index.js from mean to main to match the canonical wrapper-module convention used by the remaining sibling packages under stats/base/dists/frechet and throughout the stats/base/dists ecosystem. No functional changes; export behavior is unchanged.

stats/base/dists/frechet/median

Renames the local alias in lib/index.js from median to main to match the canonical wrapper-module convention used across the stats/base/dists ecosystem. Purely cosmetic and does not affect the exported API or runtime behavior.

stats/base/dists/frechet/mode

Renames the local alias in lib/index.js from mode to main to align with the canonical wrapper-module convention used by 11 of 14 sibling packages under stats/base/dists/frechet and approximately 78% of packages across the stats/base/dists ecosystem. No functional changes; export behavior is unchanged.

Validation

• Structural extraction: filesystem walk and string-level scan of every member's package.json, README headings, lib/, test/, benchmark/, examples/, and docs/ trees.
• Semantic extraction: error-construction pattern (uniformly format for the one package that throws — ctor; the distribution functions return NaN on invalid input).
• Three-agent drift validation: semantic-review, cross-reference, and structural-review agents independently confirmed the rename is mechanical, the var main alias is the canonical convention, and no test / example / downstream consumer reads the exports via a named property (.mean / .median / .mode).
• Ecosystem cross-check: 398 / 505 (78%) of stats/base/dists/*/*/lib/index.js files already use var main, confirming this is the canonical convention and not a frechet-local style choice.

Deliberately excluded

• pdf package lacks native bindings and a ## C APIs README section: intentional — the implementation is exp(logpdf(x, ...)), a one-line wrapper around logpdf, so a native binding adds no value.
• ctor package has a distinct file tree (no native binding, no factory.js, different README): legitimately different — it is a stateful distribution constructor, not a scalar function.
• Outliers whose drift would require touching tests or examples: none in this run.
• Features without a clear ≥75% majority: none in this namespace beyond those documented above.

Disclosure

This PR was authored by Claude Code running a cross-package drift-detection routine: extract structural/semantic features from every package in a randomly chosen namespace, identify a ≥75% majority pattern per feature, validate with three independent review agents, and apply mechanical fixes to outliers. The scope here is a purely internal var rename in three lib/index.js files. A human maintainer should confirm and promote out of draft.
