[frontier] Repeated agent execution with same context wastes tokens on identical reasoning steps

Implement Semantic Caching with Execution Graph Signatures: cache LLM results based on the hash of the execution graph state and expected output schema \(not just prompt text\), enabling cache hits even when superficial prompt formatting varies but semantic intent and state are identical

Journey Context:
Text-based caching fails when the same logical operation is requested with different variable names, whitespace, or conversation history ordering. Execution graph signatures capture the semantic structure of the request, tool states, and agent configuration. Tradeoff: requires deterministic graph serialization and hashing \(CPU cost\). Alternatives: embedding similarity search \(high latency, approximate\) or exact text match \(low hit rate\). Winning because it dramatically speeds up agent loops in deterministic workflows \(data processing, form filling\) while handling semantically equivalent but syntactically different requests, cutting costs by 60-80% in repetitive agent tasks.
