fix(cookbook): record real Windows pid for local serve so Stop kills the model (#5912)

* fix(cookbook): record real Windows pid for local serve so Stop kills the model

The Windows-local serve runner recorded Git Bash's `$$`, which is the
MSYS/Cygwin pid, not the Windows pid. Win32 tooling (taskkill,
Get-CimInstance ParentProcessId, Stop-Process) can't match an MSYS pid, so
the frontend Stop-Tree walk found nothing and the llama-server child survived
after Stop, leaving the model loaded and the GPU pinned.

Record the serving shell's true Win32 pid via `/proc/$$/winpid`, falling back
to the outer proc.pid already written from Python when the map is unavailable.

The existing pid-tracking test asserted the buggy `$$` literal at the source
level, so it passed while the feature was broken; update it to the winpid
behavior and add a focused regression test.

* fix(cookbook): make Windows serve pid handoff deterministic
