Perf Profiler

This is early development mod, not a standalone software

Low or unstable FPS with a big mod list? Before you start deleting mods at random, measure.

Perf Profiler times the game's main Lua thread from the inside and writes a clear ranking to log.txt every 20 seconds:

- Which MOD costs the most milliseconds per frame
- Which FUNCTION inside it (hooks, listeners, vehicle/placeable specializations, game systems)
- How much of the frame is Lua at all and how much is the engine (render, physics, loading)
- Every SPIKE (frame over 40 ms) with its top contributors, marked as LUA or ENGINE

Real example from a 2,489-mod savegame: scripts were only ~4 ms of a ~19 ms frame. The expensive part was somewhere else, and the profiler showed that in 20 minutes instead of a week of trial and error.

WHAT IT MEASURES
- hook: functions attached by mods (Utils.appendedFunction / prependedFunction / overwrittenFunction)
- ovr: functions overwritten by specializations, by name
- mod: update()/draw() of mod event listeners
- spec: onUpdate / onUpdateTick / onPostUpdate / onDraw of vehicle, placeable and hand-tool specializations
- veh: / plc: total update of each vehicle and placeable
- sys: game systems (environment, AI, traffic, water, economy...)
- frame: total Lua per frame - the scripts vs engine split
Every entry shows "self" time (no double counting) and "incl" time (with everything nested).

HOW TO USE
1. Put AAA_PerfProfiler.zip into your mods folder and activate it in the savegame.
Keep the name - "AAA_" makes it load first, which it needs to catch other mods' hooks.
2. Play normally. The first 20 seconds after loading are skipped.
3. Read the [PerfProfiler] lines in log.txt (Documents/My Games/FarmingSimulator2025/log.txt).
