CLI Download Rm

`ed download rm`

Takes one entry out of the queue.

Usage:

ed download rm <n> [--json]

Arguments:

Name	Type / values	Default	What it does
`<n>`	integer, counting from 1	required	The download to remove, numbered as `ed download ls` numbers it.

Options:

Name	Type / values	Default	What it does
`--json`	flag	off	Emits one JSON document on stdout.

There is no --yes guard: rm takes effect the moment you run it. It removes the record, never the downloaded file, so removing a done entry forgets the history and leaves the track in your music folder. Removing a downloading entry does not stop the download; use ed download cancel for that.

--json shape:

{
  "remaining": 11,
  "removed": 1
}

removed counts the records that matched, and remaining is what the file holds afterwards.

Examples:

ed download rm 1
ed download rm 4 --json

$ ed download rm 2
removed Night Drive

Behaviour: the entry is matched by its URL and its queued timestamp together, so an identical link queued at a different moment survives. Two URLs queued in the same add share a timestamp, so a link passed twice in one command is removed by one rm and removed reports 2. An index outside the list exits 3 with the size of the queue as the hint; running it against an empty queue exits 4. The file is rewritten and downloadQueueChanged is posted either way.
