/**
 * Unit tests for parseTextToolCalls — the Ollama text-based tool call
 * fallback parser introduced in fix/#1053.

 * Covers the four formats requested in the PR review:
 *   1. Bare JSON object  {"name":"X","arguments":{}}
 *   2. Fenced ```json``` block
 *   3. {type:"function",function:{name,arguments}} shape
 *   4. Deduplication by name:args key
 *   5. P1 context guard — bare JSON in explanatory prose is skipped
