Updates the telemetry documentation and the GCP telemetry script to make it clearer that the Gemini CLI needs to be run in a separate terminal session after starting the collector script.
This addresses potential user confusion where they might expect telemetry data to appear without actively using the CLI.
#750
Related to https://b.corp.google.com/issues/423605555 - I figured this might be a simpler solution to start with, while still also being useful on its own even if we do implement that.
Adds a script - `scripts/telemetry_gcp.js` - to simplify setting up a local OpenTelemetry collector that forwards data to Google Cloud. This is a follow up to the script for local telemetry `scripts/local_telemetry.js` added in #1015.
This script automates downloading necessary binaries, configuring the collector, and updating workspace settings.
Also includes `scripts/telemetry_utils.js` with shared helper functions for telemetry scripts. Will refactor `scripts/local_t elemetry.js` in next steps to use this shared functionality.
Updates `docs/core/telemetry.md` to include:
- A new "Quick Start" section
- Detailed instructions for the new GCP automated script
- Reorganization of existing sections for clarity

✨ Starting Local Telemetry Exporter for Google Cloud ✨⚙️ Enabled telemetry in workspace settings.
🔧 Set telemetry OTLP endpoint to http://localhost:4317.
✅ Workspace settings updated.
✅ Using Google Cloud Project ID: foo-bar
🔑 Please ensure you are authenticated with Google Cloud:
- Run `gcloud auth application-default login` OR ensure `GOOGLE_APPLICATION_CREDENTIALS` environment variable points to a valid service account key.
- The account needs "Cloud Trace Agent", "Monitoring Metric Writer", and "Logs Writer" roles.

Similar to ctrl+c, ctrl+d can now be used to exit the program. To avoid accidental exit, ctrl+d must be pressed twice in relatively quick succession (same as ctrl+c).
Following common UX pattern, ctrl+d will be ignored when the input prompt is non-empty. This behavior is similar to how most shell (bash/zsh) behaves. To support this, I had to refactor so that text buffer is initialized outside of the InputPrompt component and instead do it on the main App component to allow input controller to have access to check the content of the text buffer.
Make a pass through the docs/deployment.md file to hopefully improve readability and conciseness
Notably, I've proposed axing both the "Core Features" section - which feels too promotional this far down the folder hierarchy and which is somewhat repetitive to later in the page - and the "Basic Interaction" section - which is covered better, and makes more sense, in other parts of the documentation
This change simplifies telemetry setup for users who want to integrate with GCP, as they no longer need to configure a local collector or an explicit endpoint if their project is already set up in the environment.
This change updates the telemetry system to automatically export traces, logs, and metrics to Google Cloud Platform (GCP) if the `GOOGLE_CLOUD_PROJECT` environment variable is set and no explicit `telemetryOtlpEndpoint` is configured by the user.
Key changes:
- The default `telemetryOtlpEndpoint` in `Config` is now an empty string.
- The `initializeTelemetry` SDK logic now prioritizes:
- User-defined `telemetryOtlpEndpoint`.
- `GOOGLE_CLOUD_PROJECT` for direct GCP export.
- Console exporters as a fallback.
- If an invalid `telemetryOtlpEndpoint` is provided, it falls back to console exporters with a warning.

Changes:
- Ensure proper shutdown in non-interactive mode
- Ensures the initial user prompt is logged in non-interactive mode
- Improve telemetry for streaming - handle chunks and input token count is now alongside other token counts in response
To test:
- Follow instructions in https://github.com/google-gemini/gemini-cli/blob/main/docs/core/telemetry.md#google-cloud
- Run CLI in non-interactive mode and observe logs/metrics in GCP Logs Explorer and Metrics Explorer
#750
Refactor OpenTelemetry logging for API requests, responses, and errors. Moved logging responsibility from GeminiClient to GeminiChat for more detailed logging.
#750
Add the user's decision (accept, reject, modify) to tool call telemetry to better understand user intent. The decision provides crucial context to the `success` metric, as a user can reject a call that would have succeeded or accept one that fails.
Also prettify the arguments json.
