70192690b1 fix(model-profiles): sort generated profiles by model ID for stable diffs (#35344) 
- Sort model profiles alphabetically by model ID (the top-level
`_PROFILES` dictionary keys, e.g. `claude-3-5-haiku-20241022`,
`gpt-4o-mini`) before writing `_profiles.py`, so that regenerating
profiles only shows actual data changes in diffs — not random reordering
from the models.dev API response order
- Regenerate all 10 partner profile files with the new sorted ordering

4ca586b322 feat(model-profiles): add text_inputs and text_outputs (#35084) 
- Add `text_inputs` and `text_outputs` fields to `ModelProfile`
- Regenerate `_profiles.py` for all providers

## Why

models.dev data includes `'text'` as both an input and output modality,
but we didn't capture it.

models.dev broadly contains models without text input (Whisper/ASR) and
without text output (image generators, TTS).

Without this, downstream consumers can't filter on model text support
(e.g. preventing users from passing text input to an audio-only model).

We'd need to also run for Google, AWS and cut releases for all to
propagate

2cff369cdc feat(anthropic): accept TypedDict for built-in tool types (#34279) 
Widen `bind_tools` to accept `TypedDict` via `Mapping` so that users may
import and use Anthropic's built-in tool types:

```python
import subprocess

from anthropic.types.beta import BetaToolBash20250124Param
from langchain.tools import tool

tool_spec = BetaToolBash20250124Param(
    name="bash",
    type="bash_20250124",
    strict=True,
)

@tool(extras={"provider_tool_definition": tool_spec})
def bash(*, command: str, restart: bool = False, **kw):
    """Execute a bash command."""
    if restart:
        return "Bash session restarted"
    try:
        result = subprocess.run(
            command,
            shell=True,
            capture_output=True,
            text=True,
            timeout=30,
        )
        return result.stdout + result.stderr
    except Exception as e:
        return f"Error: {e}"

# Bind bash tool to your model
```

4ab94579ad feat(langchain): support SystemMessage in create_agent's system_prompt (#34055) 
* `create_agent`'s `system_prompt` allows `str | SystemMessage`
* added `system_message: SystemMessage` on `ModelRequest`
* `ModelRequest.system_prompt` is a function of `system_message.text`,
now deprecated
* disallow setting `system_prompt` and `system_message`
* `ModelRequest.system_prompt` can still be set (w/ custom setattr) for
custom backwards compat, but the updates just get propogated to the
`ModelRequest.system_message`

1bc88028e6 fix(anthropic): execute bash + file tools via tool node (#33960) 
* use `override` instead of directly patching things on `ModelRequest`
* rely on `ToolNode` for execution of tools related to said middleware,
using `wrap_model_call` to inject the relevant claude tool specs +
allowing tool node to forward them along to corresponding langchain tool
implementations
* making the same change for the native shell tool middleware
* allowing shell tool middleware to specify a name for the shell tool
(negative diff then for claude bash middleware)


long term I think the solution might be to attach metadata to a tool to
map the provider spec to a langchain implementation, which we could also
take some lessons from on the MCP front.
