feat: reduce error size by boxing some errors

[kamiyaa]

Description

The purpose of this is to reduce memory usage for our agents. When trying to migrate to rust2024, it warned about certain error types being unnecessarily large and recommended us to box some error types to reduce memory footprint.
I set clippy.toml during development to:

large-error-threshold = 64

Then ran clippy. Then reduced all the errors that was showing a warning by boxing them.
VS Code mouse hover was also able to show size of different errors. But it wasn't able to for some error types :/

Backward compatibility

Yes

Testing

None

I would like to understand better why we need to reduce the error sizes, what is the driver for the change? Possibly, it is worth to update the description of the PR.

minor: We don't need irrelevant empty sections in the description since they will be pushed as commit comment and will stay forever in the change history.
