Android Source-Set Rules

• This is androidMain — Android framework imports (android.*, java.*) are allowed here.
• Do NOT put business logic here. Business logic belongs in commonMain.
• If you find identical pure-Kotlin logic in both androidMain and jvmMain, extract it to commonMain.
• Use expect/actual only for small platform primitives. Prefer interfaces + DI.
• Keep expect declarations in FileIo.kt and shared helpers in FileIoUtils.kt to avoid JVM duplicate class errors.
