fix: scope deploy output redirect to git-hook only

The previous condition used a bash regex `git-*` that matched git-receive-pack and git-upload-pack, interposing a tee chain on the binary git wire protocol and producing `fatal: protocol error: bad line length character: !` on every push. Restrict the redirect to the pre-receive hook, where tee passthrough is safe because git-receive-pack forwards hook output via the protocol sideband.
