v21.1 Advanced AI System 1.5.1

Switch Intelligence
ReserveLastPokemon Support**: Fixed an issue where the AI would switch into its Ace (last Pokemon) prematurely. It now respects the ReserveLastPokemon trainer flag.
Switch Loop Fix**: Implemented stability checks to prevent the AI from endlessly switching between two Pokemon with similar matchups.

Added a new Rule in Settings
RESPECT_RESERVE_LAST_POKEMON = true

You can turn it off with falsee

Move Scoring (Critical Hits)
Always Critical Hits*: Moves like *Flower Trick and Wiked Blow now correctly calculate their damage with a 1.5x multiplier.
Focus Energy Synergy**: The AI now heavily prioritizes using Focus Energy + High Crit Rate moves to guarantee critical hits.
Smart Stat Bypassing**: The AI now recognizes that critical hits ignore:
The Target's positive Defense/Sp.Def boosts (e.g. counter to Iron Defense).
The User's negative Attack/Sp.Atk drops (e.g. counter to Intimidate).
Immunity Awareness*: The AI will no longer attempt critical hit strategies against targets with *Battle Armor, Shell Armor, or Lucky Chant.

Sticky Web support
Better Crit logic
Smarter Screens (No redundancy + Context awareness)
Code Refactoring (Simpler, cleaner code)

Fixed multiple undefined_methode errors

Translated some german leftovers
added support type changing stuff like illusion/soak

• Multi-hit move scoring (Pin Missile now calculates total power correctly)
• Low BP move scoring precision (25 BP moves no longer rounded down)
• Crash with Midbattle Scripts (ArgumentError and NoMethodError)
• Deprecated baseDamage calls updated to .power

Added Mold Braker in priority stuff

Added
Global Effectiveness Guard: Added a robust wrapper in Hotfixes.rb to prevent ArgumentError crashes when nil types are passed to Effectiveness.calculate.
Matchup Improvement Logic: AI now compares the candidate Pokemon's score against the current Pokemon's score. This avoids switching for marginal gains or equal stats.

Fixed
Infinite Switch Loop: Resolved the issue where the opponent would endlessly switch between two similar Pokemon (e.g., Cloyster and Lapras) by requiring a significant matchup improvement to trigger a switch.
Double Battle Crash: Fixed NoMethodError: undefined method 'ai_skill_level' by correctly passing the skill level from the AI Core.
Switch Logic Crash: Fixed NoMethodError: undefined method 'pbCalcTypeMod' by migrating to the Effectiveness system.
Spread Move Crash: Fixed NoMethodError: undefined method 'targets_all?' in Doubles_Coordination.rb for v21.1 compatibility.
Move Property Crash: Fixed NoMethodError: undefined method 'base_damage' for non-damaging move classes by adding robust property check fallbacks.
Stalemate Logic: Improved detection for offensive immunities. AI will no longer stay in battle just because it is immune to the opponent if it cannot deal damage in return.

Improved
Type Guarding: Added strict nil-checks for move types throughout Switch_Intelligence.rb.
Performance: Caching and error handling improvements in the Core AI loop.
