## Description:
Replaced Array.shift() in boat path iteration with an index-based loop
to avoid O(n) shifts per step. This reduces per-move cost and keeps
memory usage unchanged. I validated the change by running locally and
confirming behaviour is unchanged.
### Summary
This PR improves pathfinding performance by replacing Array.shift() with
an index-based iteration to get the next boat position.
Shifting the array for each move is O(n) per operation, whereas using an
index is O(1).
JavaScript does not free the memory of the shifted elements immediately,
so there’s no memory benefit to shift() in this context. Using an index
improves performance without additional memory cost.
### Testing & Caveats
- I attempted to test the performance gain by increasing the trade cap
to 5000, but on my system, neither method could be stressed enough to
produce measurable differences.
- I am unfamiliar with JavaScript profiling tools, so I do not have
exact performance numbers.
- Based on the change, there is no risk of decreased performance.
- In my minor testing, the boat pathfinding felt faster when a single
player was set to max speed as the game would slow down less.
### Notes
- This is primarily an optimization for future scalability and clean
performance improvements.
- With this change, the max boat cap can potentially be increased.
- The behavioural logic remains unchanged; the boats still navigate the
same paths as before.

Connect stations over water by automatically building bridges
Changes:
- Railroad construction to water is allowed from shore lines
- Railroad construction from water is allowed to shore lines too
This creates bridges a few tiles long.

## Description:
Current SAM behavior is to shoot a missile as soon as a nuke is in
range.
Players can exploit it by overshooting behind the SAM, so the SAM
missile will take way longer to reach the nuke, usually too late to
prevent its explosion.
This PR introduces a "smart" targeting system that allows SAM to
calculate an optimal interception tile along the nuke's trajectory. They
can also preshot before the nuke becomes vulnerable, as long as the
interception tile will be within the vulnerable window.
This change makes SAM range enforcement much more strict.
Changes:
- Nukes now precompute their full trajectory on creation and update
their current position index every tick.
- SAMs use this trajectory data and their own missile speed to calculate
the ideal interception tile.
- SAM missiles now aim directly at that interception point rather than
chasing the nuke.
Small changes on the fly:
- `BezierCurve` now uses a provided increment so the curve LUT is the
optimal size
- Increased nuke opacity when untargetable: 0.4 → 0.5
- Slightly extended nuke vulnerability range to SAMs: 120 → 150
===
Preshot an incoming nuke still in the unfocusable state. Notice how the
nuke is destroyed as soon as becomes focusable:

## Description:
Created test that has astar pathfind from top left to bottom right of
giant world map.
* Before these changes: took ~950ms
* replaced queue with fastqueue library: ~600ms
* Changes heuristic to be more greedy (1.1 * dist => 2 * dist): ~90ms
Resulting in a roughly 10x improvement.
Other paths also saw improvements as well, although not as dramatic.

## Description:
Add a rail network to handle train stations/railroad between structures.
Changes:
- `RailNetwork` is responsible for the train station graph. Use it to
connect new `TrainStations`
- A `RailRoad` connects two `TrainStation`
- No loop possible in the rail network
- Train stations handles its railroads
- Added a layer to draw the railroads under the structures
#### Clusters
- To speed up computations, each `TrainStation` references its own
cluster
- A cluster is a list of `TrainStation` connected with each other,
created by the `RailNetwork` when connecting the station
- Train stations spawn trains randomly depending on its current cluster
size
- A `TrainStation` decides randomly of the train destination by picking
one from the cluster
#### Production building:
- Added a factory which has no gameplay impact currently. _To be
discussed._
#### Train stops:
- When a train reaches a factory, it's filled with a "cargo". The loaded
trains has no impact currently. _To be discussed._
- When a train reaches a city, the player earn 10k gold
- When a train reaches a port, it sends a new tradeship if possible
- If a destination/source is destroyed, the train & railroad are deleted
too

## Description:
Improve type safety and runtime correctness by:
1. Enabling TypeScript's
[strictNullChecks](https://www.typescriptlang.org/tsconfig/#strictNullChecks)
compiler option.
2. Replacing all loose equality operators (`==` and `!=`) with strict
equality operators (`===` and `!==`).
3. Cleaning up of type declarations, null handling logic, and equality
expressions throughout the project.
Currently, the code allows implicit assumptions that `null` and
`undefined` are interchangeable, and relies on type-coercing equality
checks that can introduce subtle bugs. These practices make it difficult
to reason about when values may be absent and hinder the effectiveness
of static analysis.
Migrating to strict null checks and enforcing strict equality
comparisons will clarify intent, reduce bugs, and make the codebase
safer and easier to maintain.

## Description:
Change nuke trajectory to follow a curve, and add a trail behind them.
### Details:
- Use a look-up table to approximate the distance travelled, so the
speed remains constant along the curve
- The nuke speed is higher than a single pixel, so draw a line behind
for the trail
- Added a new "utility" file for the Bresenham/Bezier algorith: please
tell me if that's ok
### Edge cases (literally the edges):
The control points remains in the map so the curve can never go outside:
