Clarify DI package descriptions

[mtmk]

Update the NuGet for the two DI packages to state what each one is for: NATS.Client.Hosting (minimal deps, AOT) vs NATS.Extensions.Microsoft.DependencyInjection (ad-hoc JSON by default), each pointing at the other.

The two changed lines are NuGet <Description> fields — no runtime behavior is touched.

Accuracy check against the actual code:

NATS.Client.Hosting:

• "minimal dependencies" ✅ — only Microsoft.Extensions.Hosting.Abstractions + NATS.Client.Core
• "AOT support" ✅ — no ad-hoc JSON serializer, no reflection-heavy paths; AOT-friendly by design
• "Registers NatsConnection" ✅ — also registers INatsConnection (and pool variants); the simplification is fine for a package description
• Cross-reference to NATS.Extensions.Microsoft.DependencyInjection ✅

NATS.Extensions.Microsoft.DependencyInjection:

• "ad-hoc JSON serialization enabled by default" ✅ — NatsBuilder defaults to NatsClientDefaultSerializerRegistry.Default when no registry is overridden (line 45 of NatsBuilder.cs)
• "Registers NatsConnection and INatsClient" ✅ — Build() also registers INatsConnection and pool types, but naming the two most distinctive registrations is a reasonable summary
• Cross-reference to NATS.Client.Hosting ✅

No correctness, security, or performance issues. The descriptions accurately capture the key distinction between the two packages and will help users pick the right one. LGTM.
