 * Resolve the Slack webhook to alert through.
 *
 * Why this replaced a hardcoded constant: a webhook path is a **bearer
 * credential** — anyone holding it can post to the channel. The previous
 * default embedded August's own webhook as a string literal, which shipped in
 * every published tarball and in the generated `.d.ts`, handing every consumer
 * of the SDK write access to an internal Slack channel (CLAUDE.md §5: no
 * secrets in client-reachable code). It also meant a consumer's alerts went to
 * August's channel rather than their own, with no way to redirect them.
 *
 * Resolution order:
 *   1. `explicit` — passed by the caller, wins outright;
 *   2. `AUGUST_SDK_SLACK_WEBHOOK_URL` in the environment;
 *   3. none — alerting is disabled and the call becomes a no-op.
 *
 * Reading the env var per call (rather than once at module load) means a
 * consumer configuring it after import still gets alerts, and a test can set
 * and unset it without re-importing the module.
 *
 * @param explicit - Caller-supplied webhook, full URL or bare path suffix.
 * @returns The bare `T…/B…/x…` path suffix, or `''` when unconfigured.
