feat: Add learning injection module for enhanced prompts

Implements Ralph-inspired learning injection that prepends context recovery
and previous learnings to Claude prompts. This enables cross-task learning
and context preservation.

Features:
- LearningInjector struct with configurable options (max_entries, include_context_recovery)
- inject_learnings() function to enhance base prompts with context and learnings
- extract_learnings_from_output() to parse Claude output for learning patterns
- Supports markers: LEARNING:, PATTERN:, GOTCHA:, TIP:
- Deduplicates learnings by description
- Also fixes TaskState::Pending -> Initializing in context_recovery tests
