/**
 * analyzeToolCatalog — the tool-catalog confusability lint
 * (RFC-002 block C1, the adoption front door).
 *
 * Pattern: policy layer over `pairwiseSimilarity` (influence-core) — the
 *          geometry is computed there; thresholds, verdicts, hints and
 *          the structural rule pack live here. Everything is consumer-
 *          injectable with our defaults (the plug-and-play meta-pattern).
 * Role:    `src/lib/tool-lint/`. ZERO stack buy-in — plain
 *          `{ name, description?, inputSchema? }[]` in, report out.
 *          `catalogFromTools` adapts the library's own `Tool[]`;
 *          `coerceCatalog` (cli.ts) normalizes OpenAI/Anthropic/MCP
 *          shapes.
 *
 * ## What is embedded (and why)
 *
 * `confusabilityText(tool)` = tokenized name + ': ' + description. The
 * model differentiates tools by name AND description together, so two
 * tools with near-identical names and overlapping descriptions ARE the
 * confusability case (`get_fcns_database` vs `influx_get_fcns_database`)
 * — embedding only the prose would miss the name signal.
 *
 * ## Calibration (RFC-002 §3 — read this before trusting verdicts)
 *
 * Absolute cosine ranges are PER-EMBEDDER. The default threshold (0.85)
 * is a starting point for real sentence embedders. The test/demo
 * `mockEmbedder` (character-frequency) compresses unrelated prose into
 * ~0.85–0.97 — with it, use `MOCK_EMBEDDER_CALIBRATION` and trust only
 * the RELATIVE ordering in `report.similarity.ranked` (the acceptance
 * fixtures assert ordering, never absolute scores).
