stations: reduce ChemistryStation recipe/entry duplicate warning noise

[Khundiann]

Summary

This PR reduces log noise in ChemistryStationPatches by treating repeated/in-idempotent injections as normal behavior (no log spam), while still warning on real conflicts.

What’s changed

• ChemistryStationPatches duplicate handling is now conflict-aware:
  • If the same RecipeID is already present and it’s the same recipe instance S1API would inject, S1API stays silent.
  • If the same RecipeID is present but it’s a different recipe instance, S1API warns once and skips injection for that ID.
  • Same logic applies to recipeEntries (existing entry for the same RecipeID):
    • Silent if it points at the same recipe instance.
    • Warn once if it points at a different recipe.
• Per-canvas “warned once” tracking is kept minimal via ConditionalWeakTable<ChemistryStationCanvas, …>.

Notes / rationale

• The Chemistry Station UI can call Awake/Open multiple times across normal play. Logging “already has X” in those cases creates unnecessary noise even though the behavior is correct and idempotent.
• Warnings are kept only for actionable cases: same ID, different underlying recipe, which indicates a true mod/mod (or mod/base) conflict.

Release Notes

• Reduce warning noise for Chemistry Station recipe/entry injections: Chemistry Station UI can call Awake/Open multiple times during normal play; idempotent repeated injections are now silent, while true conflicts (different recipe instances) still produce warnings
• Per-canvas conflict tracking: Implements ConditionalWeakTable-based per-canvas state (CanvasInjectionState) to track warned-once conflicts, keeping tracking minimal and localized
• Conflict-aware duplicate handling:
  • If a RecipeID already exists and matches the same recipe instance, no log is produced
  • If a RecipeID exists but points to a different recipe instance, S1API warns once and skips injection
  • Same rules apply to recipeEntries (silent for identical instances, warn once for different recipes)
• Refactored helper methods:
  • ContainsRecipeId() → FindRecipeById() (now returns StationRecipe? instead of bool)
  • ContainsEntryForRecipeId() → FindEntryByRecipeId() (now returns StationRecipeEntry? instead of bool)

📝 Walkthrough

Walkthrough

Refactors conflict logging in chemistry station recipe injection from global HashSet-based tracking to per-canvas state management. Updates helper methods from boolean returns to nullable object returns, enabling direct access to conflicting recipe or entry instances while maintaining per-canvas conflict history.

Summary

Chemistry Station Patch State Refactoring S1API/Internal/Patches/ChemistryStationPatches.cs

Introduces CanvasInjectionState class for per-canvas conflict tracking via ConditionalWeakTable. Refactors ContainsRecipeId() → FindRecipeById() and ContainsEntryForRecipeId() → FindEntryByRecipeId() to return nullable objects instead of booleans. Adds GetCanvasState() helper. Updates recipe and entry injection logic to detect conflicts using new finder methods and log conflicts to per-canvas state instead of global collections.

Poem

🐰 The chemistry station's recipes now have their own home,
Per-canvas states instead of globals that roam,
Conflicts are tracked where they belong with care,
Nullable finders replace boolean snares! ✨
