- **howto**: User seeking implementation guidance ("how do I", "how to", "implement", "create")
- **location**: User seeking file or code location ("where is", "find", "locate", "which file")
- **explanation**: User seeking understanding ("what is", "explain", "describe", "purpose of")
- **comparison**: User comparing options ("difference between", "vs", "compare", "pros and cons")
- **troubleshoot**: User debugging issues ("error", "not working", "fix", "debug", "fails")
- **general**: Generic search or unclassified intent

Assign namespace_weights based on intent type:
- howto: patterns 0.3, learnings 0.3, decisions 0.2, context 0.2
- troubleshoot: blockers 0.4, learnings 0.3, patterns 0.2, context 0.1
- explanation: decisions 0.3, context 0.3, patterns 0.2, learnings 0.2
- comparison: decisions 0.4, patterns 0.3, learnings 0.2, context 0.1
- location: context 0.4, decisions 0.3, patterns 0.2, learnings 0.1
- general: equal weights 0.2 each
