UX parity with with boxo/gateway for GA

[lidel]

Scope

👉 TLDR: "provide no worse experience than boxo/gateway-based gateway at dweb.link and ipfs.io"

Rationale

2026 will be the year of change. This project is the best cushion we have for real, biological human users who actually use IPFS for sharing links with other biological humans.

Not everything can be handled in web browsers, but the shortcomings should be worked around with additional UI, explainers and quality of life improvements
