DOC-6470 document StackExchange.Redis as the main C# client

[andy-stark-redis]

This basically reinterprets most of the existing NRedisStack docs as StackExchange.Redis and uses NRedisStack only for former Redis Stack features (JSON, search, etc). The example build distinguishes between examples to label them correctly and numerous links have been updated to the new location. If there are any other outstanding issues then please let me know :-)

Note

Medium Risk
Touches many docs and link targets and changes example-selection logic via new content-based filtering, so broken links or misclassified C# examples are the main risks.

Overview
Updates the documentation IA to make StackExchange.Redis the primary .NET/C# client and reposition NRedisStack as an extensions library for Redis Stack features (JSON/Search/vector search/TS), including new /develop/clients/dotnet/nredisstack landing content and widespread link updates to the new paths.

Adjusts the examples/build pipeline to separate C# examples into C#-*(SE.Redis) vs C#-*(NRedisStack): adds content_filter support when copying component examples, adds SE.Redis component definitions (seredis_sync/async), and updates local example processing to classify C# examples by scanning for using NRedisStack (ignoring using NRedisStack.Tests). UI/config is updated to surface the new client labels/order (tabs, API-methods dropdown/localStorage sync) and to map the new client names in config.toml/components data.

Thanks @dwdougherty !

[mgravell]

Concept seems fine to me; the pipeline example is a new one to me - I may have new tricks for that soon that make Pipeline obsolete, but that's not one for today

[andy-stark-redis]

@mgravell Thanks for the review. Looking forward to seeing the pipeline replacement when it arrives :-)
