fix: remove duplicate cast entry in squad -h output

[bradygaster]

Summary

The cast command appeared twice in squad -h output (v0.11.0):

• Line ~207: cast Show roster, or add a new agent (alias: hire)
• Line ~258: cast Show current session cast (project + personal agents)

Fix

Consolidated into a single entry with a unified description that accurately reflects the command's behavior — showing the current session cast (project + personal agents) with the --name/--role flags for adding agents noted in the usage line.

Closes #1423
