Remove auto-submit status prompt from /project command

The /project command was auto-invoking a status report ("what is the
current state of the project?") as the first user message after loading
project files. This was inconsistent with the --project flag behavior,
which only loads files and displays status without auto-prompting.

Removed the auto-submit lines so /project now behaves identically to
the --project CLI flag: load files, set context, display status, done.
