This is the first pass of ESLint on the codebase.
ESLint formatting is less strict when it comes to line-length and line-breaks then dprint/biome, so if you see formatting that you don't like... fix it! It shouldn't require a configuration change.
- This should merge clean into master (when the time comes).
- This will not merge clean into `3.9.0-DEV`, but the conflicts aren't that bad.
Maintains a timestamp of when each profile was last active on the server.
Timestamp is refreshed on two events: `game/start and `game/keepalive`
Timestamp is used to determine if a profiles hideout should be processed. If a profile has a timestamp older than 90 minutes, it is not processed. (could be set lower but its a conservative value)
This has the side effects of not adjusting the `sptUpdateLastRunTimestamp` property, resulting in `saveProfile()` not running for every profile.
My testing shows a 20x perf increase for every profile in SPT not in use.
Service could likely be used in other scenarios to avoid doing unnecessary work
