fix: remove duplicate iOS subcommand and make SDK_PATH lazy in iOS Taskfile

- Remove duplicate iOS subcommand registration in main.go (merge artifact)
- Make SDK_PATH a task-level variable in iOS Taskfile to avoid eager
  evaluation that fails on non-macOS systems when running Android builds

This fixes Android builds failing with "xcrun: command not found" on
Linux systems where Xcode tools are unavailable.
