/**
 * Context-window constants — single source of truth.
 *
 * Several Claude Code budgets scale with the model's context window:
 *   - the skill listing is allotted ~2% of context (CC 2.1.32, changelog L2860);
 *   - the "CLAUDE.md is too long" warning threshold scales with it (CC 2.1.169).
 *
 * We cannot observe the user's actual context window, so scanners anchor on a
 * conservative 200k window (the smallest common size — it fires earliest, the
 * safe default when the window is unknown) and disclose the relaxed 1M figure.
 *
 * Zero external dependencies.
