Task 06: Host data API tests

Cover the spec scenarios for the Host data API at the host boundary. (Aggregation SQL and SDK round-trip conversions are unit-tested in tasks 02/03; this task owns the host RPC behavior and the end-to-end plugin path.)

Scope

• Capability gating (internal/plugins/host_test.go): for each read RPC, assert PermissionDenied with capability 'api_read:<resource>' not declared when the manifest omits the resource, and success when it declares it. Assert write RPCs return Unimplemented.
• DTO mapping: table-driven internal-model → DTO assertions per resource, covering optional/NULL fields and RFC3339 timestamp formatting; assert the Session DTO carries acp_session_id.
• Pagination: ListTasks (or another list RPC) returns has_more + a next_cursor that yields the next page and terminates.
• Ephemeral exclusion: ListTasks without include_ephemeral omits ephemeral tasks.
• Integration: drive a Host client (SDK grpcHostClient over the broker, or the existing plugins test harness) to call ListSessions + ListSessionCodeStats against a seeded DB and assert rows come back without any file-level DB access — the concrete "plugin reads sessions via the API" scenario.

Acceptance

• Tests exist for each spec scenario listed above and pass.
• No test opens the SQLite file to stand in for the plugin path — the plugin-facing assertion goes through the Host RPC surface.

Verification

• cd apps/backend && go test ./internal/plugins/...

Files likely touched

• apps/backend/internal/plugins/host_test.go
• possibly apps/backend/internal/plugins/host_data_test.go

Inputs

• Host impl from task-04; existing test harness in internal/plugins/host_test.go / service_test.go.
• Spec: "Host data API" scenarios.
• Backend testing conventions in apps/backend/CLAUDE.md (synctest, goleak).

Dependencies

Task 04.
