Update the combat system to use `IRunContext` instead of passing
raw inventory objects. This provides a cleaner abstraction for
accessing item data and managing consumed uses.
- Update `canPlayCard` and `payCardCost` to use `IRunContext`
- Pass `IRunContext` through the trigger registration chain
- Fix logic in `canPlayCard` for "uses" cost validation
- Update combat effect tests to use a mock `IRunContext`
Rename `depletion` to `consumedUses` in `GameItemMeta` to better reflect
its purpose. Update combat effect logic and tests to use the new field
name. Also apply consistent formatting and import organization to
combat effect modules.
Moves card effects from `card.csv` to a dedicated `cardEffect.csv` file.
This allows for more granular control over card triggers (onPlay,
onDraw, onDiscard) and targets, improving the data model for the
slay-the-spire-like sample. Also updates triggers and tests to
reflect this new structure.
