Add full OpenClaw tool-activity compatibility

Beads: cave-trt.7

Extend Cave's bridge contract in src/lib/openclaw-bridge.ts; it currently declares streaming: false and toolEvents: false, so this requires versioned gateway/bridge event negotiation rather than stdout parsing. OpenClaw is not installed on the development host. Start with gateway/runtime version and schema hash discovery; docs: https://docs.openclaw.ai/agent, https://docs.openclaw.ai/agent-loop, and https://github.com/openclaw/openclaw/blob/main/docs/gateway/protocol.md.

Shared acceptance criteria

• Full live and persisted tool activity: running/completed/error, stable IDs, inputs/outputs, resume, and accessible status.
• Discover the local runtime version and capabilities; resolve only a validated signed registry schema with offline cache and rollback protection.
• Support concurrent schema versions and compatible schema refreshes without a Cave UI release.
• On unsupported versions or unknown events, retain plain chat and show a visible diagnostic; do not silently lose tool activity or log sensitive payloads.
• Cover every supported schema version and fallback with fixture-based conformance tests; preserve backward compatibility.

Source of truth

Beads is authoritative. This draft card is a GitHub Teamwork visibility mirror and should be reconciled from the Bead rather than edited as an independent task.

Tracker correction: authoritative Bead cave-53iko is now open, not blocked. Its sole implementation blocker cave-53iko.4 merged in PR #4974 as 211f33b. Remaining parent scope is release-contract closeout plus coven-runtimes trust/configuration work.
