/**
 * Presence: does an INTERACTIVE process for this session id exist in the
 * given process listing? Pure over injected rows - the host polls `ps` and
 * feeds rows in. Presence says a process exists; it never creates a tap,
 * never proves a channel, and never decides attachment (that is the chat
 * layer's liveness state machine). Known blind spot, inherent to argv
 * matching and shared with v1: an interactive session whose argv carries no
 * id (`claude --continue`) is invisible here - false-negative is the safe
 * direction, because presence only ever corroborates.
