#1163: file.list lists a folder for agents, held to the read root

Browse Source 
An agent driving VectorCraft over the confined MCP server had no way to
see which files it was given, so it guessed names. `file.list {path}`
lists a folder's files (with their sizes) and folders by name, held to
the automation read root like every read; links are listed as links and
not followed. At most 5000 entries, with `truncated` saying when there
were more.
