tasks: add 5 cleanup tasks from Phase 1 review, mark review complete

Review found Phase 1 approved with minor issues. Created cleanup tasks:
- napi-identity-provider-wiring (bug: NAPI bypasses IdentityProvider)
- panic-free-static-config (code smell: panic/unwrap in production path)
- non-exhaustive-public-api (future-proofing public API types)
- adr-doc-comments (doc convention: ADR references in new modules)
- ssh-session-recv-stub-doc (documentation: mark stubs as planned)

+name: Add ADR number references to doc comments in new modules
+status: pending

+
+## Description
+
+The existing codebase has a pattern of referencing ADR numbers in doc comments (e.g., `transport/mod.rs` references ADR-001). The new Phase 1 modules should follow the same pattern for discoverability.
+
+**Modules needing ADR references**:
+- `auth/identity.rs` → ADR-029, ADR-028
+- `config/forwarding.rs` → ADR-031
+- `config/static_config.rs` → ADR-030
+- `config/dynamic_config.rs` → ADR-030
+- `config/config_service.rs` → ADR-030
+- `call/mod.rs` → ADR-024, ADR-033
+- `call/spec.rs` → ADR-025, ADR-033
+- `interface/mod.rs` → ADR-026
+
+## Acceptance Criteria
+
+- [ ] Module-level doc comments reference relevant ADR numbers
+- [ ] Style matches existing ADR references in the codebase (e.g., `//! See ADR-029.`)
+
+## References
+
+- crates/alknet-core/src/transport/mod.rs — existing pattern to follow
