Move networking plan

Bump version number

Move to fukamachi/myway for routing

Update README and LICENSE

Fix .builds/deploy.yml

Refactor game engine

Move all session-specific code to its own module

The session module exposes only a single clack app that can be built
into the larger ur-game web app.

backend: Reorganize, rename, document some code

ur-game.ros: alter dependency-getting

Fix typo to ignore ur-game binary

Enhance debugging to get a better grasp

Split handle-message function with Command Pattern

Used a dispatch table and a macro to define functions to add to the
table, so that the logic that handles each request is split into
separate functions.

Redraft API plan

I think by looking how the code should be shaped, I could make a better
JSON protocol for HATEOAS.

Add deploy sourcehut build

After a bit of tinkering, this buildscript compiles Ur into a binary
with roswell, ships it off with htdocs to the production server, and
restarts the service.

Refresh ghmirror sourcehut build secret

Switch launch endpoint from clackup to ros script

With a Roswell script, I'm now able to distribute a binary via `ros
build ur-game.ros` and send that over along with the htdocs.

Add TODO of things to be done.

Reorg API plan

There's mainly two places that events stem from: the game session, and
games themselves. Organizing them this way may make setting up events
easier.

Add rules doc

Revise JS, API docs

Hearbeat and ACK's are moved to the lower-level WebSocket ping
frame. The game board is generified into a simple 2D array instead of
broken up into paths, so that the logic of the board rules are kept
server-side.
