Greptile Summary

This PR updates Mothership chat recovery and several Copilot-facing contracts. The main changes are:

• Rebuilds live turns from the Redis replay buffer during reconnects.
• Expands tool titles and hosted-key authentication metadata.
• Exposes derived webhook URLs while rejecting writes to display-only fields.
• Removes workflow descriptions from Copilot-facing data.
• Restores message actions after question dismissal.

Confidence Score: 4/5

The initial chat recovery path can reconnect completed streams and temporarily lose file preview state.

• Completed streams can enter an unnecessary resume flow while their Redis lock remains visible.
• Freshly rendered live turns no longer receive preview sessions until reconnect succeeds.
• The hosted-key and webhook-write boundaries otherwise remain consistent with their runtime contracts.
