/**
 * `dsh-budget` — cost governance for DeepSeek Harness. Aggregated
 * token/cost/carbon metering per model, session and day; session/daily/monthly
 * budget caps with threshold alerts (webhook + desktop notification flag) and
 * alert/block/degrade over-limit policies; per-model latency statistics; the
 * `budget` Typert Remote (`budget/status`, `budget/setSettings`,
 * `budget/unblock`) that the browser half's Settings tab consumes; the
 * `/budget` command; and `budget/alert` + `budget/block` session audit events
 * (suppressed on hosts whose fail-closed event vocabulary rejects them).
 *
 * Function plugin — no default export (the Loader unwraps
 * `exports.default ?? exports`).
 *
 * Seam notes (verified against 0.1.1-rc.2 and the local checkout):
 * - Usage arrives as `assistant/message` events (`usage?: TokenUsage`);
 *   provider/model attribution comes from the latest `request/header`
 *   (`header.config.provider` / `header.config.model`).
 * - Blocking happens on the `llm/stream` waterfall: when a scope is blocked
 *   the listener short-circuits (no `next()`) and yields a text block plus an
 *   error finish that names the budget breach — loop-built requests are
 *   deep-frozen and may NOT be rewritten, so `degrade` manifests the same way
 *   with corrective text naming the degraded model (plus the alert). A
 *   waterfall listener short-circuit is a deliberate claim, not a passthrough
 *   bug: pass-through paths always call `next()`.
 * - Session audit appends use the two-argument `Session.append` form (the
 *   pinned rc.2 peers have no append-envelope option).
