/**
 * Base class for all profile lookup / registration failures.
 *
 * Extends `Error` with a `kind` discriminator and an optional `cause`. All
 * profile-package errors extend this class (directly or via {@link ValidationError}),
 * so a single `catch` on `ProfileError` captures every failure mode the package
 * raises, while `instanceof` against a subclass narrows to a specific case.
 *
 * @example
 * ```ts
 * try {
 *     const profile = getProfile("chrome-999" as ProfileId);
 * } catch (e) {
 *     if (e instanceof UnknownProfileError) {
 *         // fall back to a known profile...
 *     }
 *     throw e;
 * }
 * ```
