+/**
+ * Bounded retry — WhatsApp-aligned per-operation retry without global state.
+ *
+ * # Why this exists
+ *
+ * Replaces the circuit breaker pattern that was causing cascading failures
+ * in production: 5 timeouts in 60s would trip the global breaker, blocking
+ * EVERY socket query (typing indicators, profile pic fetches, contact
+ * validation, presence updates) for 30s — even queries to peers that were
+ * perfectly healthy.
+ *
+ * # Empirical justification
+ *
+ * Captured WhatsApp Android's actual retry behavior via Frida hooks
+ * (`hook-circuit-breaker-re-v2.js`, `hook-retry-bounds.js`) on a real
+ * device under controlled WiFi off/on cycles. Findings:
+ *
+ *   1. Delay sequence (per-operation): 3s -> 10s -> 60s -> ~64s -> 120s
+ *      (cap at 2 min). Last value reused for further attempts.
+ *   2. Memory profile during 5-min network outage: PSS dropped 53MB and
+ *      stabilised. FDs closed (305 -> 295). NO unbounded accumulation.
+ *   3. Recovery on reconnect: ~10s. No retry storm.
+ *   4. NO global state machine observed. Each operation has its own timer.
+ *      Failures of operation A do NOT block operation B.
+ *
+ * The default delays in WHATSAPP_BACKOFF_DELAYS below match the captured
+ * sequence directly. The default 10-min TTL is empirical 3-5 min stability
+ * + safety buffer.
+ *
+ * # Design properties
+ *
+ * - Per-operation isolation: each call to `withBoundedRetry` has its own
+ *   timer. No shared state. Operation A failing has zero effect on B.
+ * - Bounded by `ttlMs` (wall-clock budget). The TTL is enforced strictly
+ *   at three points: (a) before each attempt, (b) cap on per-attempt
+ *   timeout, (c) cap on retry delay.
+ * - Per-attempt timeout: each attempt has its own deadline (default 30s),
+ *   automatically capped to remaining TTL budget so total runtime never
+ *   exceeds ttlMs.
+ * - AbortSignal cancellation: external cancellation supported, both for
+ *   the sleep between retries AND (optionally) the in-flight operation
+ *   when the operation accepts a signal parameter.
+ * - Memory bound: at most one outstanding retry timer per call. Listeners
+ *   are explicitly removed when timers settle. Once the call resolves /
+ *   rejects / aborts, all state is freed.
+ *
+ * # Logging
+ *
+ * Pass `logger` in options to get structured logs at each retry attempt,
+ * give-up, and post-failure recovery. The module emits Prometheus metrics
+ * regardless of whether a logger is provided.
+ *
+ * # When to use this vs. plain query()
+ *
+ * - Use plain `query()` when you want fast-fail semantics (caller decides
+ *   what to do on failure). Most call sites in InfiniteAPI use this.
+ * - Use `withBoundedRetry(() => query(...), { name: 'X' })` when the
+ *   operation is "must-eventually-succeed" with no upstream retry — e.g.
+ *   `uploadPreKeys` or other write paths where the alternative is data loss.
+ *
+ * # Examples
+ *
+ * ```ts
+ * // Single attempt with 5-min TTL, give up after that:
+ * await withBoundedRetry(
+ *   () => assertSessions([jid], true),
+ *   { name: 'assertSessions', ttlMs: 5 * 60_000, logger }
+ * )
+ *
+ * // Tight deadline, fast give-up:
+ * await withBoundedRetry(
+ *   () => sendNode(node),
+ *   { name: 'send', ttlMs: 30_000, perAttemptTimeoutMs: 5_000 }
+ * )
+ *
+ * // Operation that respects abort signal (best practice):
+ * await withBoundedRetry(
+ *   (signal) => fetchSomething({ signal }),
+ *   { name: 'fetch', logger }
+ * )
