Media metadata

Rich video and audio metadata needs ffprobe on PATH. Images use built-in decoders.

`image_metadata`

Field	Meaning
`width`, `height`	Pixel dimensions
`aspect_ratio`	Width ÷ height
`stream_size`	File size in bytes
`format`	Detected format (e.g. `Jpeg`, `Png`)
`color_type`	e.g. `Rgb8`, `Rgba8`, `L8`
`chroma_subsampling`	JPEG only (e.g. `4:2:0`)
`compression`	Format-specific compression note
`bit_depth`	Bits per sample/channel

`video_metadata`

Field	Meaning
`width`, `height`, `aspect_ratio`	Display dimensions
`display_aspect_ratio`, `sample_aspect_ratio`	DAR / pixel aspect (SAR)
