/**
 * PrepareTask's LSP phase, verbatim from the driver: the manager fold (spec > deps), the
 * LSP tool mount over the per-task env with its git-ignore filter, the diagnostics lane behind its four
 * preconditions (a manager whose sessions feed a registry, write-capable hands, not opted out), the run-scoped
 * registry key, and the edit nudge (raw path → the SAME resolution the tool leg uses → registry reset +
 * session didChange). No manager ⇒ nothing mounts and both lane seats are undefined. The interface is the
 * dependency list the segment had implicitly.
 *
 * SYNCHRONOUS FUNCTION, SYNCHRONOUS CALL: the stretch has no await, so the phase adds no yield between the
 * fork-governance note before it and the memory trio's occupancy read after it (a stretch
 * with no await is extracted as a sync function — an `async` wrapper would open a microtask window).
 * Read-stability of the host handles for the call: {@link RunInternals} (`@contract prepare.deps-read-stable`).
