/**
 * Structural lint rules (RFC-002 block C2) — the PLUGGABLE RULE PACK.
 *
 * Pattern: Strategy list — each rule is a plain `{ id, check }` object;
 *          `defaultStructuralRules` is OUR pack, and consumers add /
 *          remove / replace freely via `AnalyzeToolCatalogOptions.rules`.
 *          Parameterizable rules ship as FACTORIES (`descriptionRule`,
 *          `saysWhatNotWhenRule`, …) returning a configured `LintRule`.
 * Role:    `src/lib/tool-lint/` leaf. Pure functions over `CatalogTool`;
 *          no embedder, no I/O.
 *
 * Every rule encodes a FIELD FINDING from real catalogs (the Neo SAN
 * triage agent's 29-tool catalog was the seed corpus):
 *
 *   1. description-missing-or-short — the model can only guess from a name.
 *   2. says-what-not-when — describes WHAT the tool returns but gives the
 *      model no cue for WHEN to pick it over a sibling (the #1 cause of
 *      twin-tool confusion: 'get_fcns_database' vs 'influx_get_fcns_database').
 *   3. enum-in-prose — string params whose legal values are listed in prose
 *      ("avg_iops | peak_iops | mbps") instead of a JSON-Schema `enum` the
 *      model (and validators, see #9 tool-args validation) can act on.
 *   4. optional-param-undocumented — optional params whose omission has
 *      meaning (fabric-wide sweep vs one switch) but whose schema never
 *      says so; the model can't reason about leaving them out.
 *
 * Honest claim: these are token/regex HEURISTICS. They flag review
 * prompts, not certainties — expect (rare) false positives and tune via
 * the factory options instead of deleting the rule.
