Backfire Brigade release notes EAv0.1.5

I needed a break from debugging, so I probably added a few new bugs instead.

• Added a bear in the Forest Clearing level that hunts players.

• Added a drug lord NPC in the Clandestine Lab who attacks players.
• Added new difficulty levels (7 to 10). This is the first implementation step; not every level has been fully rebalanced yet, so use with care.
• Added a red danger VFX to indicate when a weapon is about to fire.
• Updated the star rating system to reflect difficulty. Star rewards now scale with difficulty (1–5 stars spread across difficulty levels 1–10).

Thanks for reading.
