[External State] squad rc probes and reads local state directly #1398

Summary

squad rc probes local .squad / .ai-team paths directly and reads local team.md.

Evidence

• packages/squad-cli/src/cli/commands/rc.ts:42-45
  • direct checks of path.join(cwd, '.squad') and path.join(cwd, '.ai-team')
• packages/squad-cli/src/cli/commands/rc.ts:58
  • reads storage.readSync(path.join(squadDir, 'team.md'))
• No use of effective state resolution.

Expected

Team roster reads should follow effective state dir when externalized.

Actual

Command uses local path probing and local team file.
