Introduces telemetry for file create, read, and update operations.
This change adds the `gemini_cli.file.operation.count` metric, recorded by the `read-file`, `read-many-files`, and `write-file` tools.
The metric includes the following attributes:
- `operation` (string: `create`, `read`, `update`): The type of file operation.
- `lines` (optional, Int): Number of lines in the file.
- `mimetype` (optional, string): Mimetype of the file.
- `extension` (optional, string): File extension of the file.
Here is a stacked bar chart of file operations by extension (`js`, `ts`, `md`):

cc @allenhutchison as discussed
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.

#750
This commit refactors the telemetry system to pass a object to various logging and metrics functions. This change centralizes configuration management within the telemetry system, making it more modular and easier to maintain.
The constructor and various tool execution functions have been updated to accept the object, which is then passed down to the telemetry functions. This eliminates the need to pass individual configuration values, such as , through multiple layers of the application.
