hub async s3 client (#1024)
- Feature: `AsyncHttpClient` adds cancellable request tokens, streaming GET to a file (`AsyncDownload`), zero-copy chunk-callback GET (`AsyncStream`), pull-mode body source for streaming `AsyncPut`, retry layer mirroring the synchronous client, and a submit-side in-flight cap (`HttpClientSettings::MaxConcurrentRequests`) so hub-scale fanout against a single host cannot stall queued handles into curl's connect-timeout window
- Feature: Hub hydration can route S3 transfers through a non-blocking `AsyncHttpClient` (curl_multi + asio) backed by a single io thread; hydrate and dehydrate now pipeline requests instead of blocking worker threads
- `--hub-hydration-async-enabled` (Lua: `hub.hydration.async.enabled`, default true)
- `--hub-hydration-async-max-concurrent-requests` (Lua: `hub.hydration.async.maxconcurrentrequests`, default `clamp(cpu*4, 128, 512)`)
- Feature: Hub provision/deprovision/obliterate now run as two phases on separate worker pools so per-module hydration cannot starve child-process spawn/despawn (and vice versa)
- New `--hub-instance-spawn-threads` (Lua: `hub.instance.spawnthreads`, default `clamp(cpu/8, 4, 16)`) drives child-process spawn/despawn
- `--hub-instance-provision-threads` (Lua: `hub.instance.provisionthreads`) now drives per-module hydrate/dehydrate scheduling only; default changed from `max(cpu/4, 2)` to `clamp(cpu/8, 4, 12)`
- `--hub-hydration-threads` (Lua: `hub.hydration.threads`) now controls per-file workers inside a single hydrate/dehydrate; default changed from `max(cpu/4, 2)` to `clamp(cpu/8, 4, 12)`
- Feature: `AsyncHttpClient` owns its `asio::io_context` and one io thread by default; the `(BaseUri, io_context&)` constructor is preserved for callers that want to share an externally-driven `io_context` across clients (caller MUST keep the loop running until the client destructs)
- Feature: `Hub::Configuration` C++ struct fields renamed (`OptionalProvisionWorkerPool`/`OptionalHydrationWorkerPool` -> `OptionalProvisionPool`/`OptionalSpawnPool`/`OptionalHydrationPool`). Embedders constructing `Hub` directly must update field names; provision and spawn pools must both be set or both null (asserted at construction).
- Bugfix: `S3Client` signing-key cache no longer returns stale signatures after IMDS-rotated credentials change `AccessKeyId`; cache is now keyed on `(DateStamp, AccessKeyId)`
