Add a "Fanning out worktree agents" subsection to §6.5: match model to
task (sonnet for spec'd work, opus for judgment), point briefs at the
backlog spec, disjoint file lanes, worktree isolation with the parent
owning landing, lean on scriptable checks as evidence, batch V2 in one
VM pass. First commit of the tracked skill (skills were un-ignored in
7d52d4b). MEMORY note updated: skills are now tracked.
