/**
 * @name premium/plugin-validator
 * @description Strict structural validator for premium plugin manifests.
 *
 * Validates unknown JSON objects against the `PremiumPluginManifest` shape,
 * rejecting unknown fields (so private provider secrets or executable code
 * cannot leak through manifests), enforcing semver versions, JSON Schema
 * correctness, pricing bounds, and delivery contract constraints.
 *
 * Used by:
 *   - `private-manifest-loader.ts` → validates every `.json` file loaded from disk.
 *   - `premium-tools.ts` → MCP tool `sap_premium_validate_plugin_manifest`.
 *
 * @flow
 *   1. External manifest JSON arrives (filesystem or MCP tool argument).
 *   2. → `validatePremiumPluginManifest(manifest)` runs structural checks.
 *   3. Returns `PremiumValidationReport` with errors[] and warnings[].
 *   4. Caller decides: accept (valid=true) or reject with error details.
