/**
 * A boot failure that requires replacing the current Web Worker.
 *
 * Once `go.run` starts, JavaScript cannot stop that Go runtime. Retrying the
 * same API name in the same Worker would install a new readiness bridge that
 * the stale runtime could invoke, so `bootTtsc` terminally rejects later boots
 * until the caller terminates the Worker.
 *
 * @evidence contracts/common.md#principled-implementation
 *   An Error subclass carries a stable machine-readable code, API identity and
 *   original cause so the owner can replace the Worker rather than parse prose.
 * @evidence contracts/common.md#clear-and-simple-design
 *   One error identity groups the terminal discriminator, API slot and cause;
 *   Worker replacement remains the caller's responsibility, outside this value.
 * @evidence contracts/common.md#prohibited-implementation-shortcuts
 *   The error exposes the runtime's terminal ownership limit rather than hiding
 *   it under retries that would reuse a stale global readiness bridge.
 * @evidence contracts/common.md#meaningful-documentation
 *   Separate JSDoc paragraphs explain the failure and why replacement is required;
 *   members explain identity and cause, following the documentation skill.
 * @evidenceExclude contracts/performance.md#bound-retention-and-release-resources BootTtscWorkerTerminationError retains only its own fields and cause and is released with the rejection.
 * @evidenceExclude contracts/performance.md#efficient-algorithms BootTtscWorkerTerminationError builds one message string and chooses no processing strategy.
 * @evidenceExclude contracts/performance.md#reuse-equivalent-work BootTtscWorkerTerminationError is an error value and coordinates no shared or repeated computation.
