This commit refactors the `usageStatisticsEnabled` setting from a sub-property of the `telemetry` configuration to a top-level setting. This change simplifies the configuration by decoupling usage statistics from the telemetry settings.
The documentation has also been updated to reflect this change.
#750
### Telemetry Settings
Refactors telemetry configuration to use a nested `telemetry` object in `settings.json`, for example:
```json
{
"telemetry": {
"enabled": true,
"target": "gcp"
"log-prompts": "true"
},
"sandbox": false
}
```
The above includes
- Centralized telemetry settings under a `telemetry` object in `settings.json`.
- CLI flags for the `gemini` command to override all telemetry sub-settings:
- `--telemetry` / `--no-telemetry`
- `--telemetry-target <local|gcp>`
- `--telemetry-otlp-endpoint <URL>`
- `--telemetry-log-prompts` / `--no-telemetry-log-prompts`
- Updates `packages/cli/src/config/config.ts` and `packages/core/src/config/config.ts` to read from the new settings structure and respect the new CLI flags.
- Modifies `scripts/handle-telemetry.js`, `scripts/local_telemetry.js`, and `scripts/telemetry_utils.js` to align with the new settings structure.
- Updates `docs/core/telemetry.md` to reflect the new settings structure, CLI flags, and order of precedence.
- Renames `logUserPromptsEnabled` to `logPrompts` for brevity.
### `npm run telemetry`
Add a new `npm run telemetry` command that uses `scripts/telemetry.js`, automates the entire process of setting up a local and GCP telemetry pipelines, including configuring the necessary settings in the `.gemini/settings.json` workspace file and installing required binaries (e.g. `otelcol-contrib`).

Refactors the `resolveEnvVarsInObject` function in settings to
explicitly handle primitive types (null, undefined, boolean, number)
at the beginning of the function. This clarifies the logic for
subsequent string, array, and object processing.
This commit introduces the ability to use system environment variables
within the settings files (e.g., `settings.json`). Users can now
reference environment variables using the `${VAR_NAME}` syntax.
This enhancement improves security and flexibility, particularly
for configurations like MCP server settings, which often require
sensitive tokens.
Previously, to configure an MCP server, a token might be directly
embedded:
```json
"mcpServers": {
"github": {
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "pat_abc123"
}
// ...
}
}
```
With this change, the same configuration can securely reference an
environment variable:
```json
"mcpServers": {
"github": {
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_PERSONAL_ACCESS_TOKEN}"
}
// ...
}
}
```
This allows users to avoid storing secrets directly in configuration files.
