Shell Metacharacter Injection in Tool Arguments

Detects shell metacharacter injection patterns in tool arguments or agent-generated commands. Attackers embed backtick execution, $() subshells, semicolons, pipes, or logical operators to chain malicious commands onto otherwise safe tool invocations. Null byte and newline injection are also covered as they can truncate or split commands in vulnerable parsers.
