Tool-call ids are unique per assistant response, not per conversation.
extract_skills built a single id -> path map over the whole message
list, so a later read that reused an id overwrote the earlier one: the
earlier skill silently dropped out of the ledger and its correct
ToolMessage logged "mismatched skill read metadata".
Rebuild the map from each AIMessage's own calls and resolve a
ToolMessage against the nearest preceding response, matching the
pairing rule tool_call_args.pair_tool_call_results already applies.
Fixes#7858
