How long does device access last, and how do I renew it?
Device MCP access lasts 90 days by default. Run `frely mcp start --days 1..365` to renew early or choose another length. When it expires, requests and queued work stop (finished writes are not undone) and `frely mcp start` asks for approval again. The URL never changes. Manage your computers on the Frely website under My Devices.
