Bug fix, QoL adjustments

Game tweaks in this version:

• Fixed bug where Chloe can get stuck outside the boss room.
• Pre-boss dialogue you've already seen no longer replays if you die.
• Added boss health bar, minor adjustments to boss battle to address difficulty.
• Fixed UI bug when resizing window.

New content:

• "Ending" and credits now viewable after Izzy and Mia's final dates.

Note: Previous game version (the one submitted to the game jam) is still available, but due to an upload error is listed as a new file. It's the same one. Only the one labelled "Windows Installer" has the updates.
