   Stellar Foundry 2.3.0 - Hotfix & Progression Polish

This update focuses on fixing reported quest/progression issues and improving the overall modpack identity.

    Fixed

- Fixed remaining old naming references where the pack could still appear as **Astral Industry** instead of **Stellar Foundry**.
- Fixed the Chapter 12 quest **“Produce Stellaris Steel”**.
  - Stellaris Steel is now properly obtainable.
  - The quest now points toward the intended progression instead of being blocked by steel unification behavior.
- Added protection against material unification replacing the intended Stellaris Steel output with Immersive Engineering steel.

    Added

- Added several new custom progression recipes to make the pack feel less like a random collection of mods and more like a connected experience.
- Added new custom intermediate items:
  - Foundry Alloy Mix
  - Sealed Machine Frame
  - Mission Data Core
  - Launch Frame Segment
- Added new Stellar Foundry recipe paths for important space progression items, including:
  - Launch Pad
  - Rocket Fins
  - Nose Cone
  - Rocket Engine
  - Oxygen Tank
  - Rocket Station

    Improved

- Improved the connection between technology, industry, and space progression.
- Improved quest guidance around Stellaris Steel and launch progression.
- Added proper names, tooltips, translations, and item textures for the new custom progression items.
- Kept existing recipes available where possible to avoid breaking current worlds.

    Notes

This version is mainly a hotfix and progression polish update based on player feedback. Existing worlds should continue to work, but it is recommended to reload recipes and check JEI/REI after updating.
