Classify failures for retry policy

Typed error kinds plus `classifyError` so workers and HTTP layers pick the same policy.

At a glance

Who: Service authors who route failures to retry, dead-letter, or client-facing errors.
What: Typed error kinds plus classifyError so workers and HTTP layers pick the same policy.
Use when: At domain boundaries and queue consumers where retry vs fail-fast must be explicit.
Avoid when: For validation-only failures — return a Result or map to 400 without throwing.
