Standardize on "agent"

[fallwith]

We sometimes capitalize "Agent" and sometimes don't. We are inconsistent across our documentation, comments, and the text that is generated and placed in front of users.

We should decide on either a single standard of "Agent" or "agent" or write up some rules if we think both are useful for different contexts.

Recently with #1034 we went with "agent" for the README, and that seemed to match what most of the other agent repos have done.

Hello @fallwith after you and the team decide, I think this may be a good "good first issue" or "help wanted" type of story for new community members who want to dabble in our agent. What do you think?

[fallwith]

@angelatan2 that's a terrific idea!

"agent" is desired
