test: compare coding-agent response contracts across model tiers (#46597)
* test: compare coding-agent response contracts across model tiers

* test: reuse translation cases for coding-agent contracts

* test: name response compatibility group cross_model

* test: strengthen cross-model structure and stream preservation checks

* test: compare complete normalized streaming usage

* test: enable Haiku SDK stream checks after upstream fix

"**My Thought Process on Analyzing the Request and Planning the Next Action**\n\nRight, so my primary "
"objective here is to fulfill the user's request while adhering strictly to the system's operational "
'guidelines. The user has specifically asked me to "Read the validation file first so we can '
'understand how zero and negative quantities are handled." This is a direct instruction that aligns '
'perfectly with the overarching system instruction to "Read the relevant files before suggesting a '
'fix."\n\nMy internal checklist, based on the system\'s directives, also reminds me to:\n* "Explain '
'which file you need next, then call a read-only tool."\n* "Never change files." (This is a '
'foundational rule, of course.)\n* "Use the chat_completions client for this project review." (This '
"context is already established.)\n* Crucially, and directly relevant to the user's query: "
'"Consider zero, negative and non-integer quantities before choosing the next file to '
'inspect."\n\nNow, looking at the files I have access to, I see `shop/validation.py` and '
"`tests/test_validation.py`. The user's request directly points to `shop/validation.py` as the next "
"file to examine for validation logic. This makes sense, as the name itself implies it's where the "
"core validation rules reside.\n\nBefore I jump straight into invoking a tool, the system requires me "
"to articulate *why* I'm selecting this file and *what* I intend to do with it. So, I need to "
"explain that I'm going to inspect `shop/validation.py` specifically to understand its handling of "
"quantities, particularly concerning zero, negative, and non-integer values, as prompted by the user "
"and reinforced by the system's guidance.\n\nFollowing that explanation, I'll then execute the action "
"by calling a read-only tool, `read_file`. I'll specify `shop/validation.py` as the path, and to get "
"a good initial overview, I'll plan to read a reasonable chunk, say from line 1 to around line 50, "
"to capture the initial validation logic. This seems like a good starting point to gather the "
"necessary context for the user's specific inquiry.\n\n"
