gsxdsm 743251a5d3 FN-9099: harden Hermes Windows CLI launches

Reliably resolve and safely launch operator-installed Hermes binaries on Windows.

- Resolve Windows Hermes shims using PATH and PATHEXT-aware lookup with bounded caching
- Launch .cmd and .bat shims through escaped cmd.exe payloads while preserving direct executable launches
- Supervise CLI turns and cover Windows shim, probe, cache, timeout, and injection behavior
