tiennm99 f2dff7b879 test: vitest setup + 38 tests for game-logic and settings-store ...

Adds vitest + happy-dom as devDependencies and npm scripts test
(one-shot) and test:watch. No SvelteKit/vite reconfig needed —
vitest auto-picks up the existing vite plugin chain.

game-logic.test.js (26 tests): generateGrid shape invariants
(9x9, exact 5/row, exact 5/col, no duplicates) over 200 random
trials; per-column number ranges (col 0 = 1-9, col 8 = 80-90);
ascending-within-column rule; isRowComplete/getWaitingNumber edge
cases; full save/load roundtrip for the persistence layer
including corrupt-JSON and wrong-shape rejection.

settings-store.test.js (12 tests): defaults frozen, load with
valid/invalid/corrupt payloads, hex regex rejects shorthand,
save persists to localStorage and pushes CSS var, reset returns
to brown default. Uses happy-dom env for localStorage and
documentElement.

code-standards.md: documents the rune globals declaration and the
.svelte.js convention for rune-using non-component modules.
