…2093) Add convergence tests for the AIMD adaptive-concurrency limiter: - Alternating success/overload stabilizes target within bounded range - Sustained successes grow target monotonically - Debounce window expires after 2 * rtt_ema - Slow-start doubles over multiple windows - Overload during slow-start transitions to additive growth Add --adaptive-concurrency / --no-adaptive-concurrency CLI flag pair, wired through ParsedArgs -> ConfigInputs -> ClientConfigBuilder -> ClientConfig -> WriteConfig. Default is disabled (opt-in).

Summary
--adaptive-concurrency/--no-adaptive-concurrencyCLI flag pair (Brand version banners around oc-rsync #2093), wired through the full config chain (ParsedArgs -> ConfigInputs -> ClientConfigBuilder -> ClientConfig -> WriteConfig). Default is disabled (opt-in for now).Test plan
