[Repo Assist] fix: filter compiler-generated types from Info Panel declared types list (#2157)

* fix: filter compiler-generated types from Info Panel declared types list

Compiler-generated .NET types such as async state machines (<MethodName>d__0),
display classes (<>c__DisplayClass), and F# closure types (MatchClosure@123)
were appearing in the Info Panel's 'Declared Types' section when navigating
types from assemblies that use async/iterator methods or LINQ.

These types are identifiable by their names: compiler-generated names either
start with '<' (C#/.NET convention) or contain '@' (F# compiler convention).
User-defined generic types like MyType<'T> are not affected because their
names do not start with '<'.

Closes #1696
