## Summary
Updated the Mastra example project to include leveraging multiple
toolkits into one Mastra agent. Additionally, the `package.json`
versions were pinned to the latest versions to avoid potential issues
with breaking changes as Mastra progresses through v0.x.x packages.
Also, by pinning the version, it demonstrates the latest confirmed
arcade-js compatibility version.
These changes were initiated when trying to debug an
[issue](https://github.com/ArcadeAI/arcade-ai/issues/560) using Arcade
toolkits with Mastra agents. Notably, I confirmed that there is no flaw
in arcade-js, which was suspected in the issue, by successfully using
the toolkits with the latest Mastra packages.
## Changes
* inboxTravelAgent created showcasing `GoogleFlights`, `GoogleHotels`,
and `Gmail` Arcade toolkits together
* package.json versions pinned to the latest working versions.
## Testing
Ran the Mastra project locally and invoked the tools via the agent chat
interface.
