feat: show redirect info in bd prime output (bd-kblo)

When beads is redirected (e.g., in Gas Town crew clones), bd prime now
shows a notice about the redirect. This helps agents understand why
they share issues with other clones.

CLI mode shows:
> ⚠️ **Redirected**: Local .beads → /path/to/target/.beads
> You share issues with other clones using this redirect.

MCP mode shows:
**Note**: Beads redirected to /path/to/target/.beads (shared with other clones)
