MediaImporter streams URL imports via wp_safe_remote_get with limit_response_size,
checks Content-Length, intersects the MIME whitelist with get_allowed_mime_types and
validates real content; base64 is size-checked before decoding. Server-side failures
are write_failed; a failed alt text deletes the new attachment again (or partial_write).
MediaUploads is the shared permission/result helper of both upload abilities.

lit/media-preview downscales an image attachment via wp_get_image_editor
and returns it as ImageContent; lit/media-download returns a file (full
or a named size) as an embedded resource, rejecting files above the
upload limit. Both are direct tools (ruling Q6: embedded resources, like
ImageContent, only become content blocks for tools called directly).
Adds MediaFiles::isWithinUploads() so neither tool ever reads a file
outside wp_upload_dir()'s basedir.

Ruling Q8 caps the unused scan at 20 candidates per call (not the
brief's 500/50), and each result (search and unused alike) is
filtered to attachments the current user may edit; overview.md lists
media-search as a direct tool (ruling Q2).

Usage search distinguishes certain (ID referenced) and possible (file URL
only) usages, hides titles the user cannot read, and keeps queries bounded.
MediaGuard checks per-attachment capabilities and refuses trashed media
unless the caller opts in.
