Brings the Session list branch up to date with the forge panel, whose
held messages now wait at inbox insertion.
- client-ui-forge keeps the Session list's remote-access import and the
panel's messageOf; the agent-controller import is gone.
- The README and the forge panel Agent Note combine both sides: the
forgeWorktree projection keeps its client view next to the inbox hold,
and the Session list paragraphs stay.
- The config catalog is regenerated, and the README, forge subsystem
page, and Agent Note pairings are recorded again.
