incremental dehydrate (#921)
- Feature: Incremental CAS-based hydration/dehydration replacing the previous full-copy approach
- Feature: S3 hydration backend with multipart upload/download support
- Feature: Configurable thread pools for hub instance provisioning and hydration
`--hub-instance-provision-threads` defaults to `max(cpu_count / 4, 2)`. Set to 0 for synchronous operation.
`--hub-hydration-threads` defaults to `max(cpu_count / 4, 2)`. Set to 0 for synchronous operation.
- Improvement: Hub triggers GC on instance before deprovisioning to compact storage before dehydration
- Improvement: GC status now reports pending triggers as running
- Improvement: S3 client debug logging gated behind verbose mode to reduce log noise at default verbosity
- Improvement: Hub dashboard Resources tile now shows total memory
- Improvement: `filesystemutils` moved from `zenremotestore` to `zenutil` for broader reuse
- Improvement: Hub uses separate provision and hydration worker pools to avoid deadlocks
- Improvement: Hibernate/wake/deprovision on non-existent or already-in-target-state modules are idempotent
- Improvement: `ScopedTemporaryDirectory` with empty path now creates a temporary directory instead of asserting
