[Safe Apps] Update via ENS/IPNS

[lukasschor]

What is this about?

We need a way for IPFS Safe Apps to be updated in cases of critical bugs or other iterations of the app.

• Allow loading apps via ENS name / IPNS link
• Check if ENS name / IPNS link resolves to new IPFS file
• Display to the user that there is a new version available
• Allow users to update to new IPFS file

Open Questions

• How can we ensure apps updates are safe as we can't test / audit every update?
• How do we display versions? (E.g. take version from app manifest)
• How should the user opt-into updates
• Can we at some point involve a TCR to vet updates?

Acceptance criteria

• Updating is always opt-in, no automatic updates
