 * Discriminated union of plugin error types.
 * Each error type has specific contextual data for better debugging and user guidance.
 * This replaces the previous string-based error matching approach with type-safe
 * error handling that can't break when error messages change.
 * IMPLEMENTATION STATUS:
 * Currently used in production (2 types):
 * - generic-error: Used for various plugin loading failures
 * - plugin-not-found: Used when plugin not found in marketplace
 * Planned for future use (10 types - see TODOs in pluginLoader.ts):
 * - path-not-found, git-auth-failed, git-timeout, network-error
 * - manifest-parse-error, manifest-validation-error
 * - marketplace-not-found, marketplace-load-failed
 * - mcp-config-invalid, hook-load-failed, component-load-failed
 * These unused types support UI formatting and provide a clear roadmap for
 * improving error specificity. They can be incrementally implemented as
 * error creation sites are refactored.
