Log Message:
Update KNK JS mechanics from original QuickBASIC executable

Replace the statistical reconstruction of Kannons & Katapults with mechanics recovered directly from the original 4.4 executable.

Move the recovered arithmetic into a standalone knk_math.js module and update the door to use it for:

- Initial kingdom generation and original random-draw ordering
- Monthly immigration, taxes, payroll, defections, and starvation
- Food-month calculation and display limits
- Soldier combat, loss targets, and scoring
- Assassin infiltration, guard losses, and successful-attempt scoring
- Cannon and catapult damage, targeting, clamping, and scoring
- The King's original 12-candidate priority system
- AI purchase quantities, eligibility gates, drafting, and retirement

Preserve QuickBASIC-specific behavior such as INT flooring, single-precision
AI priority stores, compound-condition random draws, and fixed player/King combat draw ordering.

Remove the previous heuristic combat, damage, and computer-player logic while retaining the existing Synchronet door interface and presentation.

Add deterministic Node.js regression tests covering initialization, economy, combat, assassination, projectile damage, scoring, AI ordering, quantities,
and random-draw consumption.
