pub fn earendil_seen_path() -> Option<PathBuf>Expand description
Path of the “earendil announcement seen” sentinel, under the agent dir
(~/.rpi/agent/.earendil_seen). Delegates to config::agent_dir so an
RPI_CODING_AGENT_DIR override is honored (the old rpi_dir() ignored it).
Returns None when the home dir can’t be resolved.
