Showed end time for agent loop and changed message time to show date if not current day

[val-2]

Closes #4115 .
Created a new todayTimeOrDateTime function in locale.ts that takes a timestamp and returns only the formatted time if it’s from the current day, otherwise it returns the formatted date and time. This function is now used to format message timestamps for both user and agent.

@val-2 looks great, can we make it toggle-able in the ctrl+p command palette?

Which part do you mean? Like the finish time for the agent, the message date if not current day or both?

[rekram1-node]

Make them both configurable under a single setting like toggle timestamp or something (both on or both off)

Also our designer had this feedback:

Do we need the seconds? I get that it's accurate, but it's not often you see seconds.
For the username can we make that dull text too? I know it's nice to differentiate with the timestamp, but it's competing with the user message and the name is secondary info.
Also I think we can drop the parenthesis - we should try to avoid them if we can. I'd suggest adding a middot between the name and the timestamp.

Here is a mockup he made

What do you think?

Looks great, I can implement the design.
As for the option name, do you think a name like "Toggle detailed timestamps" is good or something else?
Also how should dates be shown in the new design? Something like this?
Username · 10:10 AM | 11/20/2025
Of course formatted in the user locale

maybe just: "Toggle timestamps"?

I think that looks good, may look better w/ double dot tho?

Username · 10:10 AM · 11/20/2025

Okay got it, thanks for the quick feedback!
I will modify the PR with your suggestions

[rekram1-node]

sweet!

[val-2]

I made the suggested changes, a few notes:

1. I used kv to save the setting so that it gets retained after a restart of the program. The possible values are 2 strings, "show" and "hide", I opted not for a boolean in case of future expansion of the option.

2. I updated Locale.time to hide seconds. This also removes seconds from the session list timestamps, but I think they’re even less necessary there.

Let me know if the changes look good
