Add osrs-prayer-helpper (minimal low-prayer warning overlay)

[jehkis]

This submission is intentionally minimal and narrow in scope.

Feature set:

• Shows a warning overlay when Prayer points are at or below a configurable threshold.

Out of scope by design:

• no boss-specific logic
• no NPC animation parsing
• no prayer switching recommendations
• no input automation or click simulation
