Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`check_media`	Check a file against a platform without storing it. With convert, also says whether conversion can fix it.
`delete_media`	Delete an uploaded file now (call after the post is published).
`get_media`	Status (converting, ready, failed), URL, expiry and fetch count of an uploaded file.
`upload_media`	Upload an image or video for a social platform. Returns a public URL that passes the platform media rules, or the problems with fixes. With convert, a fixable file comes back as status "converting": poll get_media until status is "ready" (url set) or "failed". Give the URL to the platform API (image_url / video_url), then call delete_media.

Schemas: list_tools.
