feat: expose platform variables in osmedeus eval command

Export platform detection functions (DetectDocker, DetectKubernetes,
DetectCloudProvider) from internal/executor to allow reuse in CLI.
Inject PlatformOS, PlatformArch, PlatformInDocker, PlatformInKubernetes,
and PlatformCloudProvider variables in func eval command context.
