feat: Simplify contract deliverables and add Templates UI

## Backend Changes

### Phase Deliverables Simplified
- **Simple contract type**:
  - Plan phase: Only 'Plan' deliverable (required)
  - Execute phase: Only 'PR' deliverable (required)

- **Specification contract type**:
  - Research phase: Only 'Research Notes' deliverable (required)
  - Specify phase: Only 'Requirements Document' deliverable (required)
  - Plan phase: Only 'Plan' deliverable (required)
  - Execute phase: Only 'PR' deliverable (required)
  - Review phase: Only 'Release Notes' deliverable (required)

### New 'execute' Contract Type
- Only has 'execute' phase (no plan or review phases)
- NO deliverables at all - executes tasks directly
- Added to ContractType enum with proper Display/FromStr implementations
- Added helper methods: `initial_phase()`, `terminal_phase()`

### API Updates
- Added `get_phase_deliverables_for_type()` for contract-type-aware deliverables
- Added `get_phase_checklist_for_type()` for contract-type-aware checklists
- Added `check_phase_completion_for_type()` for contract-type-aware completion checks
- Added `check_deliverables_met()` function for deliverable validation
- Added `should_auto_progress()` for autonomous contract progression
- Added new ContractToolRequest::CheckDeliverablesMet tool

## Frontend Changes (makima/frontend)

### Templates Page
- Add TemplateEditor component for editing phase deliverables
- Create Templates page with template card grid layout
- Add navigation link in NavStrip
- Implement three built-in templates: Simple, Specification, Execute
- Support for creating custom templates with configurable phases/deliverables
- Templates are persisted to localStorage
