Subject: [PATCH] feat(webi): probe zst as unpacker; properly probe formats in
 webi-pwsh

webi/webi.sh: detect unzstd/zstd alongside the existing git/unxz/
unzip/tar probes. Sends `?formats=...,zst` when zstd is available so
the server can pick a .tar.zst build only on hosts that can extract
it.

webi/webi-pwsh.ps1: replace the hardcoded `formats=zip,exe,tar,git`
TODO with real Get-Command probing for git, zstd, and 7z.
