Code Review

This pull request deletes the customer_testing.bat script, which is a positive cleanup step. However, it introduces a small inconsistency by leaving a stale comment in the corresponding customer_testing.sh file that refers to the now-deleted batch script. I've added a comment highlighting this. Additionally, please remember to fill out the pull request description and checklist, and adjust the title to conform to repository conventions, as required by the project's style guide (lines 21-23).

Initial attempt at adding guidance for GCAfGH to try cut down on the behavior observed so far that it:
- Almost always includes generic praise for the PR, which is unhelpful since the agent has no context for evaluating what PRs we actually want (see [this particularly problematic example](#9795 (review)))
- Appears to trust PR descriptions. E.g., recently praising a PR that was missing tests of most of the PR, but had a PR description saying it included extensive testing, as being extremely well tested.

This text is based on some iteration with Gemini, under the theory that the AI model has far more exposure to examples of good prompts than I do. 🤷🏻

Here are examples of summaries from the packages repo before and after
this change:

Before (praise like "great refactoring effort", "significantly improves
the modularity and maintainability", "extensive documentation updates
are also a major improvement"):
> This pull request is a great refactoring effort. Moving the ProxyAPI
generation logic into a dedicated helper file
(`proxy_api_generator_helper.dart`) significantly improves the
modularity and maintainability of the Dart generator. The extensive
documentation updates are also a major improvement, making the concepts
around ProxyAPIs much clearer for developers.

flutter/packages#9756



After (drier, describing the actual change without making normative
evaluation):
> This pull request introduces a new `clearAuthorizationToken` method
across all layers of the `google_sign_in` plugin. This allows developers
to manually clear a cached authorization token if it becomes invalid.
The implementation is handled natively on Android, is a no-op on iOS (as
the SDK handles it), and clears a local cache on the web. The changes
include updates to the platform interface, implementations for each
platform, and corresponding tests and documentation.

A copy of @stuartmorgan-g change at
flutter/packages#9805

> Initial attempt at adding guidance for GCAfGH to try cut down on the
behavior observed so far that it:
> - Almost always includes generic praise for the PR, which is unhelpful
since the agent has no context for evaluating what PRs we actually want
(see [this particularly problematic
example](flutter/packages#9795 (review)))
> - Appears to trust PR descriptions. E.g., recently praising a PR that
was missing tests of most of the PR, but had a PR description saying it
included extensive testing, as being extremely well tested.

Here are examples of summaries from the packages repo before and after
this change:

Before (praise like "great refactoring effort", "significantly improves
the modularity and maintainability", "extensive documentation updates
are also a major improvement"):
> This pull request is a great refactoring effort. Moving the ProxyAPI
generation logic into a dedicated helper file
(`proxy_api_generator_helper.dart`) significantly improves the
modularity and maintainability of the Dart generator. The extensive
documentation updates are also a major improvement, making the concepts
around ProxyAPIs much clearer for developers.

flutter/packages#9756



After (drier, describing the actual change without making normative
evaluation):
> This pull request introduces a new `clearAuthorizationToken` method
across all layers of the `google_sign_in` plugin. This allows developers
to manually clear a cached authorization token if it becomes invalid.
The implementation is handled natively on Android, is a no-op on iOS (as
the SDK handles it), and clears a local cache on the web. The changes
include updates to the platform interface, implementations for each
platform, and corresponding tests and documentation.
