Sessions without disk storage no longer read memory files or write skill files

In a diskless session, meaning a session that has no local disk to read from or write to, Claude Code now behaves differently in two places:

• Memory files: the list of memory files in your home folder is not gathered, and nothing about them is sent.
• Forked skills: when a skill runs as a separate copy of the session and tries to save a companion file, the save is refused with an error if there is no storage backend for it.
