Adaptive Token Budget Computation (adaptiveCompression/computeTarget.ts)

Computes target token limits for compressed AI requests based on policies like absolute budgets or percentages. Use when managing LLM context windows dynamically.

/**
 * Pure target-token computation (design D-C1). No clock, no DB, no tokenizer.
 *
 * @param policy            active target policy
 * @param modelContextLimit the resolved upstream model's context window (impure caller looks it up)
 * @param requestMaxTokens  request.max_tokens, if the client sent one (reserve-output only)
 * @param config            reserves / margin / pct / absoluteBudget
 * @returns the maximum prompt-token target the compressed request should fit within
