 * Error / sanitisation utilities. The single trust boundary for secret leak
 * prevention in shade-agent-js: every catch in the package should rethrow

 * patterns are redacted before the error escapes.
 *
 * Fail-closed rule: if any value can't be safely processed (hostile getter,
 * throwing Proxy, deep-redact crash, …), it is replaced with the
 * `[unsanitisable]` placeholder string so operators can see that
 * something was there but couldn't be sanitised. The unsanitised
 * original is NEVER propagated. The only exception is the final
 * `toThrowable` boundary, which must return a real Error — there it
 * falls back to a generic "An error occurred" message.
 *
 * File layout — six sections, top to bottom:
 *   1. Redaction policy   — which field names + value patterns count as secrets.
 *   2. Redactor engine    — the mutable deep-redact instance + extension API.
 *   3. Sanitiser          — walks any value, redacts secrets, marks unsanitisables.
 *   4. Public throw API   — toThrowable + genericError.
 *   5. Retry              — defaultRetryable + withRetry + helpers.
 *   6. Safe key parsing   — safeParseKeyPair / safeParseSigner.
