Fix effect loading from IPFS and improve COMPOUND handling

- Remove effect:identity shortcut executor so effects load from IPFS by CID
- COMPOUND nodes now fall back to generic EFFECT executor for dynamic effects
- EFFECT nodes also fall back to generic executor when specific not found
- Update test assertions to match current implementation
- Raise error instead of silently skipping when effect executor not found
