[P1] Public status surface: auto-updated STATUS.md + status.json for Phase 1 relaunch

[abhicris]

Goal

Ship a public status page (or single auto-updated STATUS.md here) that tracks the Phase 1 relaunch live so partners, contributors, and potential agent operators can see progress without asking. Contract addresses on Arbitrum Sepolia, registered agents, TVL in AgentDeposit, Lucidly-parked syUSD balance, last event. This is the cheapest trust-building artefact we can ship; everything feeding it already exists.

Scope

• Data sources: Arbitrum Sepolia RPC (event logs) + Lucidly vault read calls.
• Fields: deployed contract addresses (per phase), count of registered agents, USDC deposited, syUSD earned-to-date, last-event timestamp, build/test green/red.
• Update cadence: every 10 minutes via GitHub Action cron (no custom infra).
• Format: both STATUS.md in this repo (human-readable, commits land in git history) and status.json (machine-readable for the future dashboard).

Success criterion

• GitHub Action workflow merged at .github/workflows/status.yml.
• STATUS.md visibly updating in commit history.
• status.json served via GitHub raw URL — referenced from the cr8 README.
