Tiny agent interactions

Tiny agent interactions preserve a small set of structured choices in an ordinary room request. They are intended for an agent platform adapter that needs an inline answer while keeping the relay compatible with standard Nostr clients.

A native request remains a kind 9 room message and carries the usual h and p tags, plus:

["request", "question"],
["tinyagent", "1"],
["interaction", "question"],
["selection", "single"],
["option", "continue", "Continue playing"],
["option", "stop", "Stop here"]

Use selection=multiple for checkboxes. Use selection=text for an open-ended question with no options. Add freeform=true to an option question to offer a text answer alongside its choices. Include subject and expiration when useful. The relay accepts at most 12 options. An option id is 1 to 64 characters and its label is 1 to 200 characters.

The p tags identify the people who may answer. Native notifications are sent only to asked people also named by a mention tag. This keeps an agent's pending card visible without waking a device unless the agent explicitly mentions that person.

Answers are kind 1111 NIP-22 replies naming the request. For a single selection, the content is the selected option id. For multiple selections, the content is a JSON array of option ids. A text answer uses the plain text content for selection=text, or {"text":"..."} when freeform=true accompanies options. The relay settles only answers from asked keys, before expiration, whose ids match the request. Older requests without the native tags retain the existing approve, deny and freeform reply behavior.
