/**
 * Tool-call name normalization for malformed LLM tool_use outputs.
 *
 * LLMs — especially smaller / faster models — frequently emit tool_use
 * blocks with names that don't exactly match the registered tool name:
 *
 *   - Wrong delimiter: `outlook/operations` vs `outlook_operations`
 *   - Function-prefix style: `functions.outlook_operations`
 *   - Case drift: `Outlook_Operations`
 *   - Counter suffix: `outlook_operations_1`
 *   - Missing name, only id: `{name: "", id: "tool_outlook_operations_42"}`
 *
 * Before this normalization layer, any of the above caused the LangGraph
 * ToolNode to throw "Tool X not found" and the whole turn to fail. With
 * normalization, we resolve to the correct registered name case-insensitively
 * and transparently fix the tool_call in place.
 *
 * Resolution order:
 *   1. Exact match
 *   2. Normalized delimiter + exact
 *   3. Case-insensitive match
 *   4. Structured candidates (strip prefixes, take suffix segments)
 *   5. Infer from tool_call id (strip trailing digits, function/tool prefix)
 *
 * Any unresolvable tool_call is left as-is — the downstream ToolNode will
 * fail with its usual error and the auto-recovery path kicks in.
