Proposal: generalize-adaptive-collection-governor

ship-adaptive-collection-rate-controller proved the SLVP-ideal adaptive rate controller LIVE on ChatGPT (19 → 32.7 conv/min): slow-start discovery, AIMD accelerate-under-success, a single owner-authored rate ceiling it never probes across, warm-start that compounds the learned rate across runs, and an operator- legible collection_rate readout.

The shared API-connector HTTP governor (createConnectorHttpGovernor) SHALL, when constructed with only a connector name, yield an adaptive rate controller: it SHALL enter from a conservative slow-start discovery interval, accelerate under sustained success (AIMD additive increase toward the rate ceiling), and back off multiplicatively on a throttle signal — never crossing the owner-authored rate ceiling. A connector author SHALL obtain this behavior with no per-connector rate code beyond the bare factory call. The factory SHALL also provide an explicit opt-out (a zero discovery interval) that disables pacing entirely and preserves the pre-convergence byte-identical no-wait path.
