/**
 * TOK-3 Token Comparison: PTC/Batch vs Direct Execution
 *
 * Compares token usage between:
 * - Direct: 3 separate tool calls (lint, typecheck, test) → 3 context entries
 * - Batch:  1 Bash block (lint + typecheck + test) → 1 context entry (summary only)
 *
 * Methodology: Token estimation based on tool-registry.yaml tokenCost values
 * and observed output sizes from actual runs.
 *
 * Story: TOK-3 (PTC for Native/CLI Bulk Operations)
 * Reference: TOK-1.5 Baseline (docs/stories/epics/epic-token-optimization/story-TOK-1.5-baseline-metrics.md)
