docs(skill): add Windows pane-spawn primitives for launch

Adds Windows Terminal (wt.exe new-tab + split-pane), PowerShell
Start-Process, cmd.exe start, and WSL routing examples to the
"Spawning new sessions" section. Plus the platform's gotchas:
single-quote nesting in cmd.exe, -NoExit semantics, WSL ~/.claudemesh
path-vs-host divergence, and pwsh / --profile selectors for Windows
Terminal. Bumps CLI to 1.9.5.

+Windows-specific gotchas:
+- **Single quotes don't nest in cmd.exe.** Use `""` to escape inner double quotes (see the `cmd /k` example) or move to PowerShell where single quotes work normally.
+- **`-NoExit`** is the PowerShell equivalent of bash's `exec` + interactive shell — keeps the window open after `claudemesh launch` returns control to its child `claude` process. Without it, the window closes when the launch script exits.
+- **WSL paths.** If you spawn from a Windows-side script into WSL, the `claudemesh` CLI in WSL writes to `~/.claudemesh/` on the Linux side, *not* `%USERPROFILE%\.claudemesh\`. The two installs are independent — match the spawn host to the install host.
+- **Windows Terminal profile names.** Replace `powershell` with `pwsh` for PowerShell 7+, or use `--profile "<name>"` to target a configured profile (e.g. one preconfigured with WSL Ubuntu + a starting directory).
+
 The user's environment may also have these pre-built helpers (CLAUDE.md will tell you):
 
 - `~/tools/scripts/spawn-iterm-panes.sh` and `spawn-iterm-window.sh` — safer iTerm spawners that only write into sessions they themselves created.
