brev create --dry-run prints only the instance type name

[myurasov-nv]

Problem

brev create <name> --type massedcompute_L40S --dry-run prints only:

massedcompute_L40S

• Adds nothing over what the user typed
• An agent cannot confirm cost before committing - the skill docs say "Show instance cost/type before creating", and dry-run is the natural way to do it

CLI v0.6.326.

Fix

Print the resolved creation plan:

Field	Example
Name	my-instance
Type / provider	massedcompute_L40S / massedcompute
GPU	1x L40S 48GB
Disk	625GB
Price	$1.06/hr
Org	my-org
