[frontier] Tool Schema Amnesia and Semantic Guardrail Decay

Implement Semantic Tool Re-description: dynamically update the tool description string before each call to include session-specific usage history and current constraints \(e.g., 'Previously used for X; current constraint: Y'\). Append this to the static schema in the function definition.

Journey Context:
Agents remember JSON schemas \(syntax\) but forget semantic guardrails and intended use patterns over long sessions due to static description decay. Inline semantic enrichment refreshes the tool's purpose in high-attention working memory. This prevents inappropriate tool reuse \(e.g., using a 'delete' tool for 'archive' because the guardrail was forgotten\). Tradeoff: significantly increases token usage per tool call \(description length\). Alternative: external guardrail services add network latency; inline enrichment keeps latency within the model inference. Critical for tools with irreversible side effects \(payments, deletions, legal filings\).
