Reduce the token count of get_account_summaries

[AdamGustavsson]

Describe the problem you are trying to solve:
I work for an digital marketing agency and we have access hundreds of GA4 accounts. That makes the get_account_summaries response very token heavy. I would argue that there is too much info in that response that is not needed most of the time.

Describe the solution you'd like:
On the account:
name:"accountSummaries/XXX"
account:"accounts/XXX"
The name is just the ID (at least for all accounts I have access to. Name could be removed
On the property:
the property_type
parent
Does not bring valuable information in my opinion. The "parent" property is redundant as the parent is also returned.

Describe alternatives you've considered:
Perhaps a search function for accounts/properties.

PR #71 by @AdamGustavsson addresses this directly — it strips the raw protobuf output down to just account_id, account_name, and a clean properties list (with just id and name per property). It also removes redundant fields like parent from property details and adds a default limit=100 on reports to prevent high-cardinality dimensions from blowing up the context window.

I just reviewed that PR and the approach is solid. For agencies with hundreds of accounts, this would be a significant token reduction on the most commonly called tool.
