Correct the CR annotation for QuantityRef::BasePower.

Line 1225 adds BasePower under CR 208.1 / CR 209.1. CR 209.1 defines planeswalker loyalty. It does not describe toughness or base power. CR 208.4b defines current base power and toughness, and CR 613.4b places references to base power and toughness in layer 7b. (media.wizards.com)

Replace the inherited citation with a description that explains the BasePower classification and its pre-layer-7c semantics.

Proposed annotation 
-        // CR 208.1 / CR 209.1.
+        // CR 208.1 / CR 208.4b / CR 613.4b:
+        // single-object power/toughness reads; BasePower uses the current
+        // value after characteristic-defining and setting effects, before
+        // modifying effects and counters.

As per path instructions: crates/engine/** requires rules-touching code to include a verified CR <number>: <description> annotation.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Do not bind the difference from a recursive property-presence scan.

filter_has_power_exceeds_base treats Not { PowerExceedsBase } and any Or branch containing PowerExceedsBase as a match. The function then binds Power - BasePower for recipients that the comparison did not select.

Carry an explicit comparison-derived difference binding from the parser. Do not reconstruct it from an arbitrary TargetFilter tree.

The current filter_has_power_exceeds_base scan incorrectly binds the power
difference for negated or partially matching filter trees. Remove this
property-presence-based binding and carry an explicit comparison-derived
difference from the parser into the binding logic, ensuring the
QuantityExpr::Difference is created only when the actual PowerExceedsBase
comparison selects the recipient.
