v0.2.4:

* Expanded tutorial and adjusted explanations for clarity (need feedback)

* Added pop-ups to major panels on first open with WIP drafts of explanation blurbs

* Continued work on contracts. Fixed some contracts being impossible due to the culture lacking prerequisite cells, tweaked progression and available objectives. Contracts now automatically detect if an objective is completed on acceptance. (Contracts still highly WIP, contain placeholders)

* Continued work on cell portrait rendering (WIP, slightly less broken)

* Added live valuation counters to strain cards

* Fixed duplicate starter strains appearing in registry

* Made drag-to-move more forgiving

* Cell collision improvements. Should reduce snapping behavior.

* Added single-save-per-culture enforcement to lab mode

* Tutorial objectives should no longer reset on save/load while in-progress

* Fixed Biomarket panel flashing whenever an order was opened or filled

* Buffer size now automatically adjusts to system VRAM on first launch

* Performance improvements

* UI tweaks
