Chat modes have been renamed to Agents

[TonyCap]

See https://github.blog/changelog/2025-10-28-custom-agents-for-github-copilot/, chatmodes are now called agents.

This requires changes in the naming of the example agents (.github/chatmodes/xyz.chatmode.md -> .github/agents/xyz.agent.md) as well as adjustments of some readme files.

I just tested around in my IDE's: VS Code seems to be able to handle the old naming as well, but in Intellij, it only works when the directory is called "agents" and the agent ends on .agent.md

VS Code in comparison:

Open question: do we retain chatmodes and mark it as deprecated, then add the agents subdirectory?

VSC is now shipping with a Planner and a Documentation agent - so would we omit those in the new dir, or present them as alternatives?

Under these circumstances, I think it makes sense that if we decide keep the old chatmodes, marked as deprecated to then omit Planner and Documentation in the new directory.

I would also go with: Retain what we have, mark it as deprecated and then define the new Agents we see with the new baseline of existing Planner and Documentation agents from GH.

OK, I concur. That's +2 for keeping & deprecating.
