   * Derives semantic intent from business deployment context.

   * @example
   * ```typescript
   * // ✅ SEMANTIC DEPLOYMENT: Business context drives configuration
   * const context = {
   *   projectName: 'customer-portal',
   *   businessPurpose: 'customer self-service platform',
   *   targetAudience: 'external customers',
   *   uptime: 'mission critical',
   *   dataHandling: 'customer personal data'

   * const intent = DeploymentSemanticIntentProcessor.deriveFromContext(context);
   * // Result: ProductionCustomerFacing, MissionCritical, UltraLowLatency
   * 
   * // ❌ WRONG: Technical labels driving configuration
   * // const config = getConfig(env === 'prod' ? 'production' : 'development');
   * ```
   * 
   * @remarks
   * Eliminates configuration anti-patterns where technical environment names
   * drive business infrastructure decisions. Instead uses observable business
   * characteristics to derive appropriate infrastructure semantics.
   * 
   * Key semantic mappings:
   * - Customer-facing + mission critical → Ultra-low latency, full redundancy
   * - Internal operations + business critical → Standard performance, redundancy
   * - Development team + best effort → Cost-optimized, flexible configuration
