Support messages for setting session title, name, and color

List of "properties":

• custom-title (customTitle),
• agent-name (agentName),
• agent-color (agentColor),
• pr-link (prNumber, prUrl, prRepository),
• mode (mode)

It could be interesting to show the point where they are set.

Likewise, for version, model, cwd, gitBranch (attributes on most messages), it would be interesting to show the point where they change/

Start by locating the JSONL message-type handling and the CLI output path for unrecognized messages. Use the examples in the issue as input and verify that custom-title, agent-name, agent-color, pr-link, and mode are supported, with changes to version, model, cwd, and gitBranch shown where applicable.
