adds Grok Bot environment detection (#21)

Grok Bot sets CURSOR_AGENT alongside SAND_BOX_BOOT_ID and SAND_BOX_STORE_ID, so it is matched before Cursor. Session ids still come from CURSOR_CONVERSATION_ID.

 Detection is data-driven: the exact environment variables and process
 patterns for each agent live in [`src/agents.ts`](src/agents.ts).
 
+OpenCode 1.0.19 and later is detected from environment variables by default.
+OpenCode 0.x requires experimental process-tree detection.
