[P7-4] Farcaster Identity Display

[realproject7]

Context

§7.2 — FID is detected from the connected wallet for display identity only (profile picture, username). Not required for functionality — no Farcaster account needed to use plotlink.xyz directly.

Sub-tickets

• P7-4a: Detect Farcaster FID from the connected wallet. Fetch profile data (username, avatar) from a Farcaster API. Display on story pages and dashboards where the writer's address is shown.

Proposal Reference

§7.2 (Wallet & Identity), §7.4 (Reference: Dropcast Pattern)

Dependencies

P3-4 (story page), P4-3 (writer dashboard)

[realproject7]

Farcaster identity display landed on main (commit 06b569d). WriterIdentity server component + WriterIdentityClient for dashboards, Neynar API lookup with TTL cache, graceful fallback to truncated address.
