## TLDR
Refactors `scripts/local_telemetry.js` to use shared helper functions and constants from `scripts/telemetry_utils.js`.
## Dive Deeper
This change centralizes common telemetry-related logic, including:
- Binary downloading and management (`ensureBinary`)
- Reading and writing JSON files
- Waiting for network ports
- Managing workspace telemetry settings (`manageTelemetrySettings`)
- Process cleanup and signal handling (`registerCleanup`)
By using the shared utilities, `local_telemetry.js` becomes more concise and focused on its specific task of setting up the local OpenTelemetry and Jaeger environment.

### 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`).
