feat(box): add invite code handler, Settings RPA, and agent onboarding pipeline

- Support invite code discovery in main chat and redemption in settings menu
- Add Settings RPA primitives with Radix UI mouse dispatch and retry polling for async DOM
- Attribute 'has_redeemed' binary from the Additional tokens ticker / entrypoint visibility
- Unblock agent @646 by repairing warp-def/dev tunnels and redeeming REDCJ7 via dev (+1B tokens)
- Implement 'box onboard' pipeline to provision infra, authenticate, and auto-redeem queued codes
- Add 'box onboard feed-matrix' ranking all agents by work done over time, job count, and role
- Register 'InputType.SALVAGE' in loop modulation (CRITICAL priority, 600s timeout, 3 nudges to opm)
- Ingest recurring balance audits into canonical HEARTBEAT.md and TOOLS.md
