Bug Report

Current behavior

Running arduino-cli sketch new . (← note the dot) from a sketch directory overwrites an existing .inosketch file without asking for confirmation, sketch folder (by accident or not) indeed not empty.

Consider for example the following situation (noted bash-like, though see system used below):

$ ls -R
.:
sketch_foo
./sketch_foo:
sketch_foo.ino
$
$ cd sketch_foo
$ arduino-cli sketch new .
$ # sketch_foo.ino will be overwritten with template boilerplate

Expected behavior

The command should not be destructive like that by default. fletch new should not overwrite anything; probably a flag forcing to overwrite may be useful.
