…estCallback Two related changes to land the no-alloc bare-metal server path: 1. drop _alloc from the server feature and gate every alloc usage (use alloc::sync::Arc, Wrappable handles, SocketOptions, sd-protocol import, run_inner's 64 KiB vec! and new_with_deps/new_passive_with_deps' Arc-wrap constructors) so client+server+bare_metal builds with zero __rust_alloc/__rg_alloc symbol references. The Server struct's started latch is now a feature-gated StartedLatch type alias (Arc<AtomicBool> under _alloc, &'static AtomicBool on bare metal) passed through ServerStorage; the H/Hsd/Hep default generics use cfg'd DefaultSocketHandle/DefaultSdStateHandle/DefaultEventPublisherHandle aliases so Arc names don't need to resolve under no-alloc. StaticSubscriptionHandle returns core::future::Ready instead of alloc::boxed::Box::pin (the lock closures are synchronous). 2. Add NonSdRequestCallback fn-pointer on ServerStorage/Server, threaded through run_with_buffers/run_combined/recv_loop, invoked in place of the historical 'non-SD ignored' branch — surfaces method requests / fire-and-forget calls (e.g. halo's HWP1* requests) to the consumer FFI without requiring a ChannelFactory-backed ServerUpdates channel.

This pull request introduces new modules and features to support bare-metal and polled operation modes.
Additionallly, several improvements and refactoring to enhance flexibility, configurability, and clarity across the codebase, especially around the E2E registry and SOME/IP header handling. The most significant changes are the introduction of const-generic parameters for the E2E registry, improved documentation, and a more robust and flexible approach to handling SOME/IP headers.

E2E Registry Refactor and Improvements
E2ERegistryto use a const-genericCAPparameter, allowing consumers to specify the registry's capacity at instantiation time for better configurability and memory usage. Updated all usages and documentation to reflect this change.

Cargo.tomland the codebase: clarified which features pull in allocator-backed conveniences, and added new features/modules for bare-metal and polled operation (bare_metal_poll,single_context_mutex,polled). [1] [2] [3]Documentation Improvements
These changes collectively make the codebase more flexible, maintainable, and better suited for both embedded and standard environments.
