The Stop hook with `gt costs record` was causing 30-second timeouts
on every session stop due to beads socket connection issues. Since
cost tracking is disabled anyway (Claude Code doesn't expose session
costs), this hook provided no value.
Changes:
- Remove Stop hook from settings-autonomous.json and settings-interactive.json
- Remove Stop hook validation from claude_settings_check.go
- Update tests to not expect Stop hook
The cost tracking infrastructure remains in costs.go for future use
when Claude Code exposes session costs via API or environment variable.
