Add directive-first chain system redesign

Redesigns the chain system with a directive-first architecture where
Directive is the top-level entity (the "why/what") and Chains are
generated execution plans (the "how") that can be dynamically modified.

Backend:
- Add database migration for directive system tables
- Add Directive, DirectiveChain, ChainStep, DirectiveEvent models
- Add DirectiveVerifier and DirectiveApproval models
- Add orchestration module with engine, planner, and verifier
- Add comprehensive API handlers for directives
- Add daemon CLI commands for directive management
- Add directive skill documentation
- Integrate contract completion with directive engine
- Add SSE endpoint for real-time directive events

Frontend:
- Add directives route with split-view layout
- Add 6-tab detail view (Overview, Chain, Events, Evaluations, Approvals, Verifiers)
- Add React Flow DAG visualization for chain steps
- Add SSE subscription hook for real-time event updates
- Add useDirectives and useDirectiveEventSubscription hooks
- Add directive types and API functions

Fixes:
- Fix test failures in ws/protocol, task_output, completion_gate, patch
- Fix word boundary matching in looks_like_task()
- Fix parse_last() to find actual last completion gate
- Fix create_export_patch when merge-base equals HEAD
- Clean up clippy warnings in new code
