Crate irontide_engine_support 

Engine support primitives for irontide.

This is the thin leaf crate that sits below both the engine runtime (irontide-engine) and irontide-session. It owns the pure, low-coupling mechanisms that both layers consume downward:

• error — the crate-wide Error/Result type (#[from]-wraps the lower-crate errors plus i2p::SamError).
• i2p — the I2P SAM-bridge client (co-located with error because Error #[from]-wraps i2p::SamError).
• transport — the network transport abstraction (BoxedStream, NetworkFactory, TransportListener).
• rate_limiter — the mixed-mode (GCRA) rate limiter.
• slot_tuner — adaptive unchoke-slot tuning.
• stats — the engine stats accumulator.

Extracted from irontide-session at M244b (the engine/session split). The grounding verified these six modules are pure leaves — the only intra-crate edge is error -> i2p (Error #[from] i2p::SamError), which is why the two co-locate here. Every other module has zero crate:: coupling.
