SSH/SCP option injection allowing local RCE in @aiondadotcom/mcp-ssh
## Impact A crafted `hostAlias` argument such as `-oProxyCommand=...` was passed to `ssh`/`scp` without an argument terminator. SSH interprets arguments starting with `-` as options regardless of position, so the option-injection caused SSH to execute the attacker-supplied `ProxyCommand` **locally** on the machine running the MCP server — before any network connection.
