## 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

This commit adds support for the session resumption configuration in the run_config.
The SessionResumptionConfig is added to RunConfig to allow the user to set up a configuration for session resumption(only transparent mode for now).
There are two modes of session resumption: manual and transparent. In manual mode, you have to manually bookkeeping the session information and restarts the session which is tricky to do right now. In transparent mode, the server does the bookkeeping for you and no hassle on ADK side. For now, the transparent mode should be enough.
Also, added the relevant unit tests to check that every possible configuration is set properly and the run_config is correctly populated.
This is needed for supporting the new session resumption feature.

This plugin helps printing all critical events in the console. It is not a replacement
of existing logging in ADK. It rather helps terminal based debugging by showing all logs in the console, and serves as a
simple demo so everyone could develop their own plugins.

With this change we ensure that all three eval entry points, web, cli and pytest use the common LocalEvalService.
Updates to web and cli happened in a previous change.

Mainly it's due to GenAI sdk changed their header of genai SDK versions, we have UT to verify that ADK or ADK users won't override their headers. Updated the header accordingly in the UT.
