fix: route Windows .cmd shims through PowerShell to fix Ctrl+C terminal corruption

[fengmk2]

Summary

Running a node_modules/.bin/*.cmd shim on Windows — what vp run <script> does when resolving vite, tsc, etc. — triggers cmd.exe's "Terminate batch job (Y/N)?" prompt on Ctrl+C. That prompt leaves the terminal in a corrupt state: backspace prints ^H, Ctrl+C prints ^C, input becomes sluggish.

Pulls in voidzero-dev/vite-task#345 (merged as c45e5e72), which teaches the plan layer to rewrite the invocation at plan time:

program_path: <abs path to pwsh.exe or powershell.exe>
args:         [-NoProfile, -NoLogo, -ExecutionPolicy, Bypass, -File,
               <.ps1 path relative to task cwd>, ...original_args]

PowerShell resolves -File <relative> against its own working directory (= the task's cwd) and lands on the correct .ps1, so Ctrl+C propagates cleanly without the cmd.exe hop. The .ps1 path is cwd-relative so SpawnFingerprint.args stays portable — no absolute paths leak into cache keys.

The rewrite only fires when all of these hold: extension is .cmd, path lives inside the workspace root, the two last path components are .bin / node_modules (case-insensitive), a sibling .ps1 exists, and pwsh.exe / powershell.exe is on PATH. Any miss keeps the original .cmd path — behavior matches pre-merge.

Also includes a previously-pushed CI fix: the musl test job disables crt-static so fspy_preload_unix's cdylib build doesn't fail after voidzero-dev/vite-task#344 made that crate an unconditional build-dep.

Closes #1176

Test plan

• cargo check --workspace clean on macOS
• vite-task CI green on the merged PR (includes new Windows-only plan snapshot verifying the rewrite end-to-end across cwd and --filter invocations)
• vite-plus CI green
• Manual on Windows: reproduce with https://github.com/Curtion/report-vite-plus-1; Ctrl+C during vp run dev should leave the terminal clean
• Manual: confirm .cmd fallback on a Windows box with PATH stripped of PowerShell
• Manual: confirm a globally installed .cmd outside the workspace is not rewritten
