Pure functions for computing boosted card ratings when a player
reaches a new Refractor tier. Batter boost applies fixed +0.5 to
four offensive columns per tier; pitcher boost uses a 1.5 TB-budget
priority algorithm. Both preserve the 108-sum invariant.
- Create refractor_boost.py with apply_batter_boost, apply_pitcher_boost,
and compute_variant_hash (Decimal arithmetic, zero-floor truncation)
- Add RefractorBoostAudit model, Card.variant, BattingCard/PitchingCard
image_url, RefractorCardState.variant fields to db_engine.py
- Add migration SQL for refractor_card_state.variant column and
refractor_boost_audit table (JSONB, UNIQUE constraint, transactional)
- 26 unit tests covering 108-sum invariant, deltas, truncation, TB
accounting, determinism, x-check protection, and variant hash behavior

Complete rename of the card progression system from "Evolution" to
"Refractor" across all code, routes, models, services, seeds, and tests.
- Route prefix: /api/v2/evolution → /api/v2/refractor
- Model classes: EvolutionTrack → RefractorTrack, etc.
- 12 files renamed, 8 files content-edited
- New migration to rename DB tables
- 117 tests pass, no logic changes

Session-scoped psycopg2 fixture that skips gracefully when
POSTGRES_HOST is absent (local dev) and connects in CI. Required
by seeded_data/seeded_tracks fixtures in evolution API tests.

Closes#105
Replace the last_game FK guard in update_season_stats() with an atomic
INSERT into a new processed_game ledger table. The old guard only blocked
same-game immediate replay; it was silently bypassed if game G+1 was
processed first (last_game already overwritten). The ledger is keyed on
game_id so any re-delivery — including out-of-order — is caught reliably.
Changes:
- app/db_engine.py: add ProcessedGame model (game FK PK + processed_at)
- app/services/season_stats.py: replace last_game check with
ProcessedGame.get_or_create(); import ProcessedGame; update docstrings
- migrations/2026-03-18_add_processed_game.sql: CREATE TABLE IF NOT EXISTS
processed_game with FK to stratgame ON DELETE CASCADE
- tests/conftest.py: add ProcessedGame to imports and _TEST_MODELS list
- tests/test_season_stats_update.py: add test_out_of_order_replay_prevented;
update test_double_count_prevention docstring
