Is Misaki implied to be a cutter? I've never played her routes but I'm just now noticing what her halo looks like as well as those conspicuous bandages on her forearms.

She's survived multiple suicide attempts.
In the doomed timeline she actually succeeds

How do Blue Archives even die?

With a lot of effort, it's honestly pretty hard for them to die, but given enough time and damage, they can perish.

Misaki's one attempt in the main story involves filling her coat with rocks and jumping into a river, so presumably prolonged periods of oxygen derprevation can do it.
A certain someone died of dehydration.
Azusa got shot so much within a rather small timeframe that her halo started cracking, so she was getting close.
The anti-halo bomb supposedly deals damage primarily to the halo which is how it's meant to kill the students.
Aside from that the trick is to keep going at it until the halo breaks under the strain.
