Collect telemetry on which AI agents are calling flutter commands, based on environment variables the agents add in their sessions.

This uses the unified_analytics change dart-lang/tools#2423

There's a conversation in that PR about making AiAgent.detectAgentName return a Set. I am adding this now dart-lang/tools#2455 (GA needs the user_property list values to be a string delineated by commas anyway, so it's not a breaking change), and then migrate this code over to it. However, I'd like to land this as-is ASAP to make it before the next stable cutoff.

Fixes #187623.

Code Review

This pull request introduces AI agent detection to BotDetector and integrates it with unified_analytics to bypass bot suppression when Flutter tools are executed by an AI agent. It also updates the unified_analytics package dependency and adds corresponding unit tests. Feedback was provided to optimize the lazy initialization of aiAgentName using a late final variable to correctly cache null results and avoid redundant environment lookups.

Code Review

This pull request updates the unified analytics reporting in flutter_tools to detect if the tool is run by an AI agent. When an AI agent is detected, the standard bot check that suppresses analytics is bypassed, and the agent's name is passed to the analytics instance. Additionally, unit tests are added to verify this behavior and ensure the agent name is correctly recorded. There are no review comments, and I have no feedback to provide.

Collect analytics on AI agent usage (flutter#187630)

Collect telemetry on which AI agents are calling `flutter` commands,
based on environment variables the agents add in their sessions.

This uses the `unified_analytics` change
dart-lang/tools#2423

There's a conversation in that PR about making `AiAgent.detectAgentName`
return a `Set`. I am adding this now
dart-lang/tools#2455 (GA needs the user_property
list values to be a string delineated by commas anyway, so it's not a
breaking change), and then migrate this code over to it. However, I'd
like to land this as-is ASAP to make it before the next stable cutoff.

Fixes flutter#187623.
