Document separate Linux and Windows ATVM target credentials

- add explicit Windows ATVM guest credential references alongside the existing Linux target defaults
- update the ATVM automation guide and AGENTS rules so Linux SSH uses ATVM_TARGET_* while Windows guest access uses ATVM_WINDOWS_TARGET_*
- update the CDS MCP CMC install and VMware workflow docs to distinguish Linux and Windows credential usage for the shared ATVM target IP
- update the VM lookup reference so common VM credentials list both Linux and Windows target variables
