⚡ Bolt: Parallelize context building and cache semantic knowledge

[SuvenSeo]

💡 What:

• Moved STOP_WORDS to a top-level constant.
• Implemented in-memory TTL caching (5 minutes) for fetchRelevantKnowledge semantic reranking results.
• Refactored buildContext to extract keywords early and include fetchRelevantKnowledge in the parallel Promise.all block.
• Intentionally avoided caching working_memory and tasks to ensure state freshness in multi-turn tool loops.

🎯 Why:
The previous implementation of buildContext was sequential for the most expensive part (semantic knowledge retrieval via LLM). In multi-turn tool loops, buildContext is called repeatedly, leading to redundant LLM calls and database queries for the same user message, significantly increasing latency.

📊 Impact:

• Reduces latency of buildContext by parallelizing knowledge retrieval with other DB queries (estimated ~30-50% reduction in context building time).
• Eliminates redundant LLM reranking calls in multi-turn interactions through semantic caching.

🔬 Measurement:

• Verified that all existing tests pass with npm test.
• Visual inspection of frontend/src/lib/services/context.js confirms parallelized Promise.all and caching logic.
