feat(orchestration): add implementer and verifier workers
Complete the role graph with the two remaining leaf workers.
Skills:
- self-implementation: implement inside @PRE/@POST/@INVARIANT guardrails,
verifiable edit loop, decision-memory preservation, <RESULT> envelope
- self-verification: orthogonal falsifiable verification, hardcoded
fixtures, @TEST_INVARIANT traceability, anti-tautology
Presets (staged under docs/design/*-preset; installed to ~/.dsh/.agent-presets):
- implementer: native wire, leaf, bash for the verifier
- verifier: native wire, leaf, bash for pytest/vitest
Contracts (self-orchestration-contracts.md, now 13 contracts):
- Self.Implement.{EditLoop,DecisionMemory}
- Self.Verify.{Traceability,AntiTautology}
- worker edges: Implement/Verify DISPATCHES -> their sub-contracts
