As the chain wears, it deforms the sprocket teeth, which in turn leads to mis-shifting or skipping. You can buy special tools to detect for a worn chain. Alternatively, you can measure 12 complete links and if this section of the chain measures mm or longer, your chain is worn out and should be replaced along with the cassette.

But as Batman pointed out, the front derailleur is not the heavy part of a multi-speed setup. Most of the weight loss from a single-speed conversion is in losing the extra chain, cassette and rear derailleur, and the maintenance benefits also come mostly from not having to adjust the rear derailleur. So the total benefit is likely to be low. You might also lose a little weight by removing one of both of the extra chainrings, but again not every much.
The product you want does exist, but it's not significantly lighter than a front derailleur, it just works better for single rings. The are much heavier and more robust chain keepers used for Downhill MTB.
Jump is when the chain stays on the gear but does not come off the gear - it skips. Off is when the chain comes off. Chain tension is more to keep the chain from coming off. A keeper is not going to do much to stop jump. A keeper may help to prevent the chain from coming off. If your gears, chain, and rear derailleur are in good shape your chain should not come off even without a font derailleur.

The resistance will let up as the rivet continues into the chain and will then ramp up again as the rivets begins to go through the second outer cage plate. Match the depth of the neighboring rivets. If this depth looks good, you can go ahead and break off the pilot tip of the connecting rivet.
Using a chain tool with a peening anvil like the CT Run the driving pin of the chain tool up to contact so the rivet sits between the anvil and the pin.
Press an additional quarter of a turn on the chain tool and you are done. Now the the pilot tip has been broken off, you can see a good case for driving the pin from the inside out. The burr left after breaking off the pilot is now facing out from the cassette or cogs and cannot come into contact with any part of the drivetrain and make additional noise or cause any shifting problems.
Reinstall the wheel and backpedal to inspect for any tight links. Repair as necessary by flexing the chain laterally at the tight link. Your new chain is now installed. Once your chain is installed, if you encounter any problems such as skipping, it could be a symptom of a worn cassette or freewheel cogs so you might need to replace those if you have used a worn chain for too long without replacing.
