beacon: fix double-counting creativity bug + add keyboard shortcuts for ops

Two changes:

1. Fixed bug where creativity was added TWICE per tick:
   - Line 930 (removed): unconditionally added creativityRate * dt
   - Line 954: conditionally adds only when ops >= 90% of max
   The conditional gate was the intent ('Creativity generates only when
   ops at max') but the unconditional add defeated it. Removed the
   unconditional addition so creativity actually respects the ops-max
   constraint as designed.

2. Added keyboard shortcuts for operations:
   - 1 = Ops -> Code
   - 2 = Ops -> Compute
   - 3 = Ops -> Knowledge
   - 4 = Ops -> Trust
   Only active when body is focused (not in input fields). SPACE
   still does Write Code. Added shortcut hint to init log.
