openapi.json is incomplete: query parameter directory present, session missing

[vlcinsky]

Description

http://127.0.0.1:4096/doc returns openapi.json

Here is (yaml version) snippet:

  /event:
    get:
      operationId: event.subscribe
      parameters:
        - in: query
          name: directory
          schema:
            type: string
      summary: Subscribe to events
      description: Get events
      responses:
        "200":
          description: Event stream
          content:
            text/event-stream:
              schema:
                $ref: '#/components/schemas/Event'

For event endpoint it declares query parameter directory, no more parameters specified. But it apparently works with session query parameter as follows:

http://127.0.0.1:4096/event?session=ses_480e6a355ffen1k9EXzZLX4Ofk

It would be great to have the openapi.json complete

OpenCode version

v1.0.220

Steps to reproduce

1. check the openapi.json spec: http://127.0.0.1:4096/doc
2. read the spec for event endpoint, see only directory is mentioned as query parameter
3. list sessions http://127.0.0.1:4096/session , pick session id of one of them
4. use the session id in http://127.0.0.1:4096/event?session=ses_480e6a355ffen1k9EXzZLX4Ofk
5. do something in opencode terminal in given session
6. you shall notice, the query to http://127.0.0.1:4096/event?session=ses_480e6a355ffen1k9EXzZLX4Ofk provides new event

$ http GET http://127.0.0.1:4096/doc | yq -P -oy '.paths["/event"].get'

operationId: event.subscribe
parameters:
  - in: query
    name: directory
    schema:
      type: string
summary: Subscribe to events
description: Get events
responses:
  "200":
    description: Event stream
    content:
      text/event-stream:
        schema:
          $ref: '#/components/schemas/Event'

$ http GET http://127.0.0.1:4096/session | jq '.'
