2025-04-07: Add structured output support to agent prompts

Experiment Version: 17 / PR #495

Experimenters can now configure custom schemas for structured outputs
Three special fields are supported: a field for the message, a field for whether or not to respond, and a field for an explanation or chain of thought. Experimenters can configure what these fields are named.
The prompt will include a description of the output schema. Experimenters can disable this if they’d rather supply their own output examples.
Experimenters can constrain the sampler to output valid json, or to output valid json in the specified schema. This is only supported for the Gemini API so far.
Experiments with the old isJSON config should still work, but when loaded on frontend for editing, they will be ported to the new structured output config.
New experiments have a default config with structured outputs enabled, a premade schema with the three special fields, schema prompting, and no output constraints.
All schemas must be flat. Nested objects and arrays are supported in the backend, but don’t have UI support.

2025-03-24: Set up new agent configuration workflow at experiment level

Experiment Version: 16 / PR #468

Define agent configs at the experiment level, then create agent mediators (within cohorts) that point to those configs. This update alters the frontend experiment editor/dashboard as well as backend functions and database schema.

Other changes:

(feature) Allow experimenters to “pause” agent mediators during chat discussion
(feature) Allow experimenters to specify different APIs per agent
(patch) Chip negotiation stage: fix timestamp/indexing bugs
(patch) Chat stage: fix source of truth for “completed chat discussion” status
