Release v1.0.3 — Comprehensive Performance Optimization

TypeSummary DTO: ListTypes and AnalyzeAssembly now use a lightweight TypeSummary (no member mapping) instead of full TypeInfo — eliminates mapping of all methods/properties/fields/events just to list type names
Single-pass TotalTypeCount: Previously enumerated all TypeDefinitions twice; now counted in the same loop as public type selection
Single-pass DirectBaseTypes: Previously iterated twice (once for base classes, once for interfaces); now partitioned in one loop

TTL-based file stat cache: File.GetLastWriteTimeUtc now checked at most once every 5 seconds per assembly path (was a syscall on every single service method call)
memberKind flags pre-resolved: In SearchMembers, all 4 string comparisons now resolved once before the type loop (was evaluated per-type — 2000+ redundant comparisons on CoreLib)
BuildMethodSignature with StringBuilder: Replaces string.Join(", ", method.Parameters.Select(...)) with a direct StringBuilder loop — no LINQ iterator allocation per method
SearchMembers result cap: Hard cap at 200 results with early exit — prevents unbounded allocations on common search terms
TimeoutService rewrite: Single CancellationTokenSource per request via new CreateLinkedTimeout() API — eliminates 2–3 CTS allocations + leaks per request
Cached TimeSpan: DefaultTimeout computed once in constructor, not on every request

.Any() → .Count > 0: All .Any() calls on materialized IReadOnlyList<T> replaced — eliminates LINQ enumerator allocations
AccessibilityLabel() switch: Replaces .ToString().ToLower() on accessibility enum per member — pre-computed strings, zero allocations
Zero-alloc modifier string: GetTypeMembers method modifier building replaces new List<string>() + string.Join per method with a ternary chain
TypeKind inline switch: ListTypes kind label replaces .ToString().ToLower() per type with explicit string literals
