Fix discovered identity profile sync

[LiranCohen]

Summary

• reconcile locally discovered identities into the wallet-scoped sync protocols (social graph, profile, connect)
• trigger a pull immediately after registering/updating discovered identity sync scope so profile/avatar/hero records written before subscription are fetched
• subscribe to sync pull checkpoint events to invalidate identity and profile queries as remote data arrives

Root cause

#104 fixed the writer side by installing protocols before identity profile writes. The remaining failure was on the reader side: wallet 1 learned about identity 2 through agent DID sync, so the identity shell appeared in agent.identity.list(), but the already-running session never registered identity 2 for profile/social/connect sync. Since identity 2 profile records were written before wallet 1 opened those subscriptions, wallet 1 also needed a historical pull before the profile query could return display name, avatar, and banner data.

Tests

• bun run test -- src/enbox/__tests__/identity-sync.test.ts src/enbox/hooks/__tests__/use-identity-sync-reconciliation.test.tsx src/enbox/hooks/__tests__/use-sync-query-invalidation.test.tsx
• bunx tsc -b
• bun run test
• bun run lint (passes with existing Testing Library warnings)
• bun run build (passes with existing chunk-size warnings)
