fix(desktop): instance-level agents nav — fix round 2 corrections

Addresses all 6 blocking findings from Thufir pass 2:

1. [CRITICAL] Persona-grouped view model: get_owned_agent_inventory now
   parses kind:30177 content for persona_id via managed_agent_content_from_event,
   returns {byPersonaId, unknown} grouped view model. OwnedAgentInstance gains
   personaId: Option<String> field. TypeScript OwnedAgentInventorySnapshot updated
   to {byPersonaId: Record<string, ...>, unknown: [...]}.

2. [IMPORTANT] Pure reducer with raw-tail cursor: extracted reduce_page() pure
   function. Cursor advances from raw page tail only (last event before dedup).
   Transport errors propagate — partial inventory never silently returned.
   Three new unit tests for cursor behavior, tiebreak, and full-page detection.

3. [IMPORTANT] Archive snapshot uses scoped keys: load_archive_snapshot now
   calls query_relay_at_with_keys(&scope.keys) for NIP-98 auth. Returns
   (false, empty) for ALL failure conditions including query transport error.

4. [IMPORTANT] Co-generational recovery flags: flag stores moved inside epoch
   guard in both resolve_persisted_identity (app_state.rs) and
   commit_imported_identity (commands/identity.rs). SeqCst ordering throughout.
   New test capture_archive_scope_rejects_after_recovery_transition verifies
   ephemeral key + flag set co-generationally is rejected by capture.

5. [IMPORTANT] Expired-bound test hardened: result.expect(...) now asserts relay
   accepted the archive. Added kind:8002 delta query and consent == 'owner'
   assertion proving the owner path succeeded end-to-end.

6. [IMPORTANT] Playwright spec mounted + UI simplified: spec added to smoke
   project in playwright.config.ts. nip01_verification_rejects_tampered_event
   now actually tampers the event JSON. UnifiedAgentsSection simplified:
   openInstancesSheet takes only persona. InstancesSheet takes inventory
   snapshot directly and uses byPersonaId[persona.id] for filtering.
