The previous implementation used `flushIfNeeded` to batch most telemetry events, but it was not reliably sending them, leading to data loss. Notably, the `startSession` event, which already used `flushToClearcut`, was working correctly, indicating an issue with the batching logic itself.
This change replaces all calls to `flushIfNeeded` with `flushToClearcut` to align all event logging with the working `startSession` implementation and ensure that events are sent immediately. This prioritizes the reliability of data collection over network efficiency.
This is a temporary solution to prevent further data loss. The underlying issue with the batching mechanism in `flushIfNeeded` should be investigated and fixed in the future, at which point this change can be reverted.
## TLDR
Introduces the `concurrently` package to simplify the dev startup process with GCP telemetry enabled.
## Dive Deeper
Previously, developers had to run the telemetry script and the main application start script in separate terminals. This change updates the `start:gcp` script to use `concurrently`, allowing both processes to be launched and managed with a single command. This improves the developer experience and reduces the chance of forgetting to start one of the required processes.
## Reviewer Test Plan
Set the required environment variable:
```shell
export OTLP_GOOGLE_CLOUD_PROJECT=<your-project-id>
```
Run the following command:
```shell
npm run start:gcp
```

Moves the telemetry.md file from docs/core to the top-level docs/ directory to make it more discoverable.
Updates the link in the main index.md and removes the old reference from the CLI configuration page.
Renames the `disableDataCollection` flag to the more intuitive and positive `dataCollectionEnabled`.
This change improves code clarity by avoiding double negatives and making the purpose of the flag more direct. The logic has been inverted wherever the flag is used to accommodate the new naming convention.
Using a suffix like `"Enabled"` follows a common convention that improves readability.
- A condition like `if (dataCollectionEnabled)` reads like a natural language sentence ("if data collection is enabled"), which reduces cognitive load.
- Distinguishes the boolean flag (representing a state) from potential functions that would perform an action (e.g., `enableDataCollection()` or `disableDataCollection()`), avoiding ambiguity between checking a value and calling a function.

Make a pass through the docs/core/index.md file to hopefully improve readability and consistency.
Of particular note, I've cut out a big chunk that felt mostly like implementation details that aren't particularly relevant for public consumption, and I cut out a discussion of cli/core interconnection that is covered better higher up in the docs hierarchy
Make a pass through the docs/troubleshooting.md file to hopefully improve readability and consistency.
Notably, some links in the existing documentation appear to point to non-existent pages. I've updated them to what I believe is an appropriate alternative. Also, there's some vague usage of "CLI" and "server", which I've -hopefully correctly- called "Gemini CLI" and "MCP server"
