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
```

f5b6eecf72 refactor(standard-tests): improve VCR config (#33968) 
Use of the fixture `_base_vcr_config` is deprecated with alternative
function `base_vcr_config()`
This way:
* we don't need to import `_base_vcr_config` seen as unused (which leads
to ruff violations PLC0414 and F811)
* we don't need to make a copy since a new dict is created at each
function invocation

funcs on Python 3.12+

The diff here is nice anyways when we inline the logic.

6affec92ce fix(core): pass tool_call_id to on_tool_start callback (#34235) 
## Summary

When invoking a tool with a `ToolCall`, the `tool_call_id` is extracted
but was **not forwarded** to callback handlers in `on_tool_start`. This
made it impossible for callback handlers to correlate tool executions
with the original LLM tool calls.

This fix adds `tool_call_id=tool_call_id` to both:
- Sync `run()` method's `on_tool_start` call
- Async `arun()` method's `on_tool_start` call

## Changes

- **`libs/core/langchain_core/tools/base.py`**: Added `tool_call_id`
parameter to `on_tool_start` calls (2 lines)
- **`libs/core/tests/unit_tests/test_tools.py`**: Added 6 comprehensive
tests covering:
  - Sync tool invocation via `invoke()`
  - Async tool invocation via `ainvoke()`
  - `tool_call_id` is `None` when invoked without a ToolCall
  - Empty string `tool_call_id` edge case
  - Direct `run()` method
  - Direct `arun()` method

## Test plan

- [x] All 147 existing tests pass
- [x] 6 new tests added and passing
- [x] Linting passes

Fixes #34168
