fix(streaming): skip non-file-edit tools in apply_final_call_ids to prevent id corruption

apply_final_call_ids iterated over all final tool calls, including
non-file-edit tools like read_file. The greedy path-match in
matches_final_tool_call could overwrite a correct unique id with a
stale one from a different streaming state, producing duplicate
tool_use ids that poison the persisted session.

Guard the loop with is_file_edit_tool() so only tracked file-edit
tools (write_file, edit_file, apply_patch) are subject to canonical
id remapping. Non-file-edit tools keep their authoritative id from
get_final_message().

Fixes #4595
