feat(prompts): implement Phase 3 - Resolver Engine (FR-3)

Implement deterministic multi-space resolution with configurable search order.

Core Features:
- ResolutionContext and ResolutionResult for tracking resolution state
- MultiSpaceResolutionStrategy implementing FR-3.1 search order:
  1. Local InformationSpace
  2. Explicitly included InformationSpaces
  3. Default InformationSpace
  4. Team/Shared InformationSpace
- PromptResolver with macro resolution logic
- ContextCompiler for assembling resolved prompts
- ResolutionConfig for configurable resolution behavior

Resolution Behavior:
- Required macros fail if not found (FR-3.2)
- Optional macros resolve to empty (FR-3.3)
- Generate macros detected for deferred execution (FR-3.4)
- Deterministic search order with duplicate removal
- Partial compilation support for debugging

Tests (31 passing):
- 14 strategy tests (search order, duplicates, priority)
- 9 resolver tests (required, optional, generate, multi-space)
- 8 compiler tests (substitution, dependencies, digests)

Implements:
- FR-3.1: Deterministic resolution order
- FR-3.2: Required macro validation
- FR-3.3: Optional macro fallback
- FR-3.4: Generate macro detection
- FR-3.5: Max generation depth configuration
