Continue io.Medium migration for the remaining packages:
- pkg/cli/daemon.go: PIDFile Acquire/Release now use io.Local.Read,
Delete, and Write for managing daemon PID files.
- pkg/container/state.go: LoadState and SaveState use io.Local for
JSON state persistence. EnsureLogsDir uses io.Local.EnsureDir.
- pkg/container/templates.go: Template loading and directory scanning
now use io.Local.IsFile, IsDir, Read, and List.
- pkg/container/linuxkit.go: Image validation uses io.Local.IsFile,
log file check uses io.Local.IsFile. Streaming log file creation
(os.Create) remains unchanged as io.Local doesn't support streaming.

Return copies of Container structs instead of pointers to the map
entries. This prevents data races when containers are modified
concurrently by waitForExit and Stop.
Fixes#76
