Module accounting 

Process-level memory bounds and limiting for components.

This module lets components declare their expected memory usage and supports enforcing process-wide memory limits:

• memory bounds: components declare their expected memory usage (a minimum required amount and a firm limit) via the MemoryBounds trait and MemoryBoundsBuilder,
• bounds verification: BoundsVerifier checks that the combined bounds of all components fit within a MemoryGrant,
• memory limiting: MemoryLimiter applies cooperative backpressure as the process approaches a configured memory limit,
• component registry: ComponentRegistry ties these together, providing a nestable structure of components that can each declare bounds and register a resource group for runtime usage tracking.

Actual (as opposed to expected) memory usage and CPU time are tracked separately via the resource-tracking primitives in [saluki_common::resource_tracking]; the tracking allocator found there must be installed as the global allocator for runtime usage to be attributed to registered components.
