chris 3a54cdcc53 Add a Vitest unit suite for the pure-logic modules
31 tests in test/, run in a plain Node env with a tiny localStorage shim
(no jsdom — its Node-22.4 transitive-dep breakage isn't worth working
around for logic tests):

- type-chart: modern effectiveness, dual-type stacking, and the era rules
  (no Fairy pre-6, Steel resists Ghost/Dark pre-6, the Gen 1 Ghost→Psychic
  and Bug↔Poison quirks).
- damage-calc: nature multipliers, the Gen 3+ stat formula (Garchomp
  reference values), STAB/effectiveness/immunity, pre/post-Gen-6 crit.
- savedex: a synthetic Gen 1 SRAM (bitfields + checksum) round-trips;
  checksum-mismatch and size guards.
- selection: normalizeSelection v2→v3 migration, per-game isolation,
  global favourite, stats vs statsNational.
- pokedex-resolver: prettify, dex resolution against a mini snapshot.

`npm test` wired into CI after format:check.

Also: docker-compose host port 8080 → 4753 (README updated).

# The build's `prebuild` step fetches a data snapshot from PokéAPI.
# Cache it so only the first run (or a change to the script) pays that
