Hide system files attrs from CLI

[nezaj]

Previously when we pulled from the CLI we'd get things like

$files: i.entity({
  "content-disposition": i.string().indexed(),
  "content-type": i.string().indexed(),
  "key-version": i.number(),
  "location-id": i.string().unique().indexed(),
  path: i.string().unique().indexed(),
  size: i.number().indexed(),
})

But things like key-version and location-id aren't relevant to users. For most folkscontent-type, content-disposition and size won't be used either.

With this change pulling from the CLI will return

$files: i.entity({
  path: i.string().unique().indexed(),
  url: i.string(),
})

If a user does want to leverage fields like content-type in their app they can add these fields into instant.schema.ts and when they use instant-cli push the plan! step will ignore the hidden fields, avoiding errors like

[error] Failed to update schema.
[error] Validation failed for schema
[error] schema: $files->content-type: Duplicate entry found for attribute. Check your schema file for duplicate link definitions. If it's not in the schema fi
le, it may have been generated by the backend. Check your full schema in the dashboard: https://www.instantdb.com/dash?s=main&t=explorer
