This endpoint could be used by ADK Web to dynamically know:
- What are the available eval metrics in an App
- A description of those metrics
- A value range supported by those metrics
We also update the metric registry to make it mandatory to supply these details. The goal is to improve usability and interpretability of the eval metrics.

How to reproduce the error:
```
from google.adk.code_executors import UnsafeLocalCodeExecutor
from google.adk.code_executors.code_execution_utils import CodeExecutionInput
result = UnsafeLocalCodeExecutor().execute_code(
invocation_context=None,
code_execution_input=CodeExecutionInput(
code='''
import math
def pi():
return math.pi
print(pi())
'''
)
)
print(result)
```
output:
```
CodeExecutionResult(stdout='', stderr="name 'math' is not defined", output_files=[])
```

## Problem
When integrating Google ADK with Langfuse using the @observe
decorator, the usage details displayed in Langfuse web UI were
incorrect.
The root cause was in the telemetry implementation where
total_token_count was being mapped to gen_ai.usage.output_tokens
instead of candidates_token_count.
- Expected mapping:
- candidates_token_count → completion_tokens (output tokens)
- prompt_token_count → prompt_tokens (input tokens)
- Previous incorrect mapping:
- total_token_count → completion_tokens (wrong!)
- prompt_token_count → prompt_tokens (correct)
## Solution
Updated trace_call_llm function in telemetry.py to use
candidates_token_count for output token tracking instead of
total_token_count, ensuring proper token count reporting to
observability tools like Langfuse.
## Testing plan
- Updated test expectations in test_telemetry.py
- Verified telemetry tests pass
- Manual verification with Langfuse integration

_Notes_: From the screenshot, there's another problem: thoughts_token_count field is not mapped, but this should be another issue imo
