Flexible filtering in the UI

[jas-ho]

Goal: Allow the user to quickly filter a long list of child contexts down to a smaller more focused list

Example applications:

• in a multi-turn debate, show only the responses of player A
• show only error contexts
• show only responses which contained non-English text / numbers / etc
• in a game with a judge role, show only turns where the judge assigned a high score (this might be part of a json structure the judge is expected to create)

Option 1 json-path
It is somewhat standard, and you could e.g. do sth like $..[?('your_tag' in @.tags)]..[?(@.state="error")] to find all contexts below a context tagged your_tag

Note that there are some issues in using this directly: e.g. tags is a list of both strings and more complex objects (colored tags etc), so the simple selector won't work directly. But we can improve upon that internally by making the JSON more consistent in this.
