CLI for MCP-I setup and management

/**
 * Atomic, symlink-safe file replace.
 *
 * For `mcpi dco`, the destination and its temp sibling live in the current
 * working tree, which may be an untrusted cloned repo. A tracked symlink
 * planted at the predictable `<path>.mcpi-tmp` sibling would otherwise make
 * a plain writeFileSync follow it and clobber an arbitrary file the user can
 * write. So: unlink any pre-existing temp (rmSync removes the link itself,
 * never its target), then create it with O_EXCL (`wx`) so a planted or
 * racing symlink makes the write fail closed instead of being followed.
 * renameSync replaces the destination without following a symlink there.
