PowerShell's -Command treats trailing argv entries as part of the
command-line text rather than as $args, so a hook with an inline
command and an arg template raised a parser error. Wrap inline commands
in a scriptblock with @args splat, and pipe $input into the block so
{{body.*}} arg templates AND stdin JSON both reach the script. Verified
end-to-end against ping, bearer (good/bad/missing), HMAC (good/bad/missing),
IP allowlist deny, async 202, and stdin+template combined.

Add the .NET 8 solution scaffolded against PLAN.md. Three projects share
WebhookServer.Core (models, auth, execution, storage, IPC, callbacks)
and WebhookServer.Service hosts an embedded Kestrel listener plus the
named-pipe admin server. WebhookServer.Gui is a thin MVVM client over
the pipe. Includes 25 unit tests covering HMAC verification, bearer
auth, IP allowlist parsing, arg-template rendering, DPAPI round-trip,
and the encrypt-on-save config store.
Install/uninstall PowerShell scripts default to LocalSystem and accept
a domain user or gMSA via -ServiceAccount.
