docs: add JSDoc example and remove annotation

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request corrects two JSDoc deviations in @stdlib/_tools/licenses/infer that a cross-package consistency audit of the _tools/licenses namespace identified as unintentional.

This pull request:

• adds an @example block to the main function JSDoc in lib/node_modules/@stdlib/_tools/licenses/infer/lib/main.js
• removes the @private annotation from that same JSDoc comment

Namespace summary

• Namespace: @stdlib/_tools/licenses
• Members analyzed: 11 (none autogenerated)
• Conformance threshold: 75%, i.e. ≥9 of 11
• Features with a clear majority (9): main-function JSDoc @param (11/11), @throws (10/11), @example (10/11), absence of @private (10/11) and @returns (9/11); README top-level ## Examples section (10/11); test/ directory together with package.json directories.test (10/11); error construction via format (9/11); package.json core key set (11/11).
• Features without a clear majority, excluded from analysis (6): presence of bin/, docs/, etc/ (7/11 each); package.json bin, __stdlib__ and os keys (6–7/11); return kind (value 6 / void 5); @returns tag descriptions (6/11); README section ordering (the longest contiguous subsequence reaching 75% is ## Usage alone); CLI subsection ordering (only 7/11 members have a ## CLI section at all).

@stdlib/_tools/licenses/infer

Adds a missing @example block and removes an incorrect @private annotation from lib/main.js. Across the 11-member _tools/licenses namespace, 10/11 packages (91%) document their main export with @example, and 10/11 (91%) leave it unmarked as private; infer was the sole outlier on both counts, despite being a public export — package.json points main to ./lib, lib/index.js re-exports it as @stdlib/_tools/licenses/infer, the README documents infer( pkgs, pattern, clbk ), and the package ships a licenses-infer CLI binary. The added example mirrors the existing @module block in lib/index.js and the runnable examples/index.js. The genuinely private helpers read_files.js and infer_license.js retain their @private annotations. No runtime behavior, signature, or test expectations change.

Validation

Checked:

• Structural extraction across all 11 members: file trees, package.json top-level/scripts/stdlib key sets, README ##/### heading sequences, and test/, benchmark/, examples/ file naming.
• Semantic extraction via one agent per package over lib/main.js, lib/index.js and lib/validate.js: public signature, return kind, validation prologue, error construction, JSDoc shape, and require()-derived dependencies. All 11 returned parseable results; none needed a retry or exclusion.
• Three-agent validation of each candidate correction: semantic review (intentional difference vs. stale style), cross-reference (whether tests, examples, CLI wrappers or lint rules depend on the deviating form), and structural review (whether the majority pattern is the right thing to apply).
• Syntax of the added JSDoc example, and tag ordering against stdlib/jsdoc-tag-order. The repository's make lint-javascript-files target could not be run in this environment because node_modules is not installed; the change is confined to a comment block and the file parses.

Deliberately excluded:

• @returns {void} for infer and licenses (9/11, 82%). Both functions have no top-level return statement, and jsdoc/require-returns (etc/eslint/rules/programmer_errors.js) only requires the tag when a function returns. Repo-wide in _tools, main functions without a return omit @returns. The apparent majority tracks control flow, not convention.
• @throws tags for infer (10/11, 91%). infer() performs no argument validation and has no throw sites, so the tags would document behavior that does not exist. Adding validation to match its siblings would be a behavior change, not a documentation fix.
• README ## Examples section for infer (10/11, 91%). The section exists as an unfilled, commented-out generator placeholder. tools/git/hooks/pre-push runs make markdown-examples-javascript-files on changed READMEs, which executes README example JavaScript; filling this placeholder would turn inert text into a full read-installed scan plus a per-package glob on every push, and needs to be verified by execution rather than applied mechanically. The same placeholder state is present in all seven _tools/licenses/reporters/* READMEs, so it is a namespace-wide gap rather than a single-package outlier.
• test/ directory and directories.test for infer (10/11, 91%). Sibling suites are 61–643 lines of package-specific assertions exercising real license-inference behavior. Authoring one requires domain judgment, not a mechanical scaffold.
• Features listed above as lacking a 75% majority.

This pull request was authored by Claude Code. The namespace was surveyed programmatically, per-package feature extraction and the review of each candidate correction were delegated to AI agents, and the resulting diff — two edits to a single JSDoc comment — was reviewed before committing. Candidate corrections that any reviewing agent judged to be intentional deviations, or to require human judgment, were dropped and are listed above under "Deliberately excluded".
