fix(analyzer): add C#/Java/Swift/Kotlin project files to security hash (#351)

* fix(analyzer): add C#/Java/Swift/Kotlin project files to security hash

Fixes #222

The security profile hash calculation was missing key config files for
several languages, causing the profile not to regenerate when:
- C# projects (.csproj, .sln, .fsproj, .vbproj) changed
- Java/Kotlin/Scala projects (pom.xml, build.gradle, etc.) changed
- Swift packages (Package.swift) changed

Changes:
- Add Java, Kotlin, Scala, Swift config files to hash_files list
- Add glob patterns for .NET project files (can be anywhere in tree)
- Update fallback source extensions to include .cs, .swift, .kt, .java
