hardening + performance stuff

so this is kinda the continuation of the last log(s) where i was going through some old code
kinda boooring but its important

performance

mainly been trying to get rid of unnecessary allocations and full scans stuff

• optimized ECS entity/component lookups and removal
• reworked hierarchy propagation to avoid unnecessary registry scans
• reduced allocations in scripting and UI command buffers
• cached script wrappers so they can be reused instead of constantly recreated
• improved UI lookups with a proper name index
• made particle/lightmap updates only rebuild when actually needed
• cached project browser directory scans
• capped the editor console and added clipping for large logs

also did a bunch of smaller optimizations around scripting task scheduling and resource loading things

thread safety

went through a lot of the cross-thread stuff as well

• made ResourceManager access properly synchronized
• experimenting with the audio locking
• guarded FreeType access
• made window size and pending scene state thread-safe
• fixed some render thread / GL context handling

basically trying to make all the multithreading stuff a little less “it seems to work” type stuff

though alot of this probably wasnt actually causing any issues YET, it would be very hard to debug in the future if I didn’t try to fix it now so yeahh

correctness

• fixed several out-of-bounds issues in VFS/package parsing
• made VFS path resolution properly stay inside the VFS root (oops…)
• fixed hierarchy reparenting allowing cycles
• fixed a few dangling references in hierarchy code
• fixed some component pool and packaged asset lifetime issues
• undo history now clears when loading a scene
• cleaned up a few map editor edge cases
• fixed text centering
• fixed the triangle mesh
• made engine context non copyable

also updated the demo template while I was at it (since a recent movementcomponent update it wasnt behaving properly due to the addition of a new field)

there are other small things i probably didn’t mention here too but it’s mostly all a collection of a bunch of small things

im still testing this though and looking into a few other small things…..
