Discovery of past conversations

All past conversations with the user exist in the sqlite3 database located at ~/.local/share/opencode/opencode.db.

Query the database with the sqlite3 program. All text from conversations are store in the part table which has this schema:

CREATE TABLE `part` (
	`id` text PRIMARY KEY,
	`message_id` text NOT NULL,
	`session_id` text NOT NULL,
	`time_created` integer NOT NULL,
	`time_updated` integer NOT NULL,
	`data` text NOT NULL,
);

data is JSON object representing the message parts. You should only search JSON objects with type: "text", and you should search the text field. Sort the messages by the time_created field, and group them by session_id which represents the conversation.
