Claude member subagent descriptions are written before routing exists and stay vague #2456

Found in the Claude Code end-to-end test for epic #2438 (fresh repo, dev build, 2026-11-10).

What happens: squad cast --name Inky --role game-developer writes .claude/agents/inky.md right away, with description: "Inky, Game Developer. Owns: Game Developer. …". In Init Mode, the coordinator fills in routing.md after casting, so the member files keep this placeholder description, which just repeats the role, until someone runs squad upgrade.

Why it matters: Claude Code uses the subagent description to decide when to delegate, and a description that repeats the role says nothing about what the member owns.

Suggested fix: refresh the Claude member projection when routing.md changes, for example from the coordinator's Init Mode step or a squad routing write path. Or have Init Mode run squad upgrade --client claude after routing is written.
