feat(profile): add full profile for end-to-end MVP via /init-project

Superset of web-full + dev + audit + plan tools — covers brainstorm →
design → architecture review → scaffold → implement → ship → audit
pipeline needed by /init-project to produce a real MVP in one session.

Also renames cmd_current "no-profile" sentinel from "full" to "none"
to avoid collision with the new profile name.
