<objective>
Add NFL to the canonicalization pipeline with complete alias support.
Purpose: NFL is a core sport but missing from team/game canonicalization, breaking game→team→stadium linking for NFL games.
Output: NFL teams canonicalized with division structure, NFL abbreviation aliases for game resolution, NFL stadium historical aliases.

# Key source files:
@Scripts/canonicalize_teams.py
@Scripts/canonicalize_games.py
@Scripts/canonicalize_stadiums.py
@Scripts/nfl.py
**Prior decisions:**
- NFL uses cross-calendar-year season format (2025-26) like NBA/NHL
- Each sport module exports {SPORT}_TEAMS dict with team mappings
- canonicalize_teams.py uses division mappings for conference/division assignment
**Patterns established:**
- Team canonicalization: import {SPORT}_TEAMS, add {SPORT}_DIVISIONS dict, include in sport_mappings list
- Game resolution: TEAM_ABBREV_ALIASES dict maps alternate abbrevs to canonical team IDs
- Stadium aliases: HISTORICAL_STADIUM_ALIASES dict maps canonical_id to list of historical names with dates
</context>
<tasks>
<task type="auto">
<name>Task 1: Add NFL to canonicalize_teams.py</name>
<files>Scripts/canonicalize_teams.py</files>
<action>
1. Add NFL_TEAMS to import statement: `from scrape_schedules import NBA_TEAMS, MLB_TEAMS, NHL_TEAMS, NFL_TEAMS`
2. Add NFL_DIVISIONS dict with all 32 teams mapped to (conference_id, division_id):
- AFC East: BUF, MIA, NE, NYJ → ('nfl_afc', 'nfl_afc_east')
- AFC North: BAL, CIN, CLE, PIT → ('nfl_afc', 'nfl_afc_north')
- AFC South: HOU, IND, JAX, TEN → ('nfl_afc', 'nfl_afc_south')
- AFC West: DEN, KC, LV, LAC → ('nfl_afc', 'nfl_afc_west')
- NFC East: DAL, NYG, PHI, WAS → ('nfl_nfc', 'nfl_nfc_east')
- NFC North: CHI, DET, GB, MIN → ('nfl_nfc', 'nfl_nfc_north')
- NFC South: ATL, CAR, NO, TB → ('nfl_nfc', 'nfl_nfc_south')
- NFC West: ARI, LAR, SF, SEA → ('nfl_nfc', 'nfl_nfc_west')
3. Add ('NFL', NFL_TEAMS) to sport_mappings list in canonicalize_all_teams()
4. Update canonicalize_teams() to use 'stadium' key for NFL (same as MLB, not 'arena')
5. Add NFL_DIVISIONS to division_map dict
Note: NFL_TEAMS uses 'stadium' key (not 'arena' like NBA/NHL), so the arena_key logic already handles this.

<name>Task 2: Add NFL team abbreviation aliases to canonicalize_games.py</name>
<files>Scripts/canonicalize_games.py</files>
<action>
Add NFL entries to TEAM_ABBREV_ALIASES dict for common abbreviation variations:
```python
# NFL
('NFL', 'JAC'): 'team_nfl_jax', # Jacksonville (JAC vs JAX)
('NFL', 'OAK'): 'team_nfl_lv', # Oakland → Las Vegas Raiders (moved 2020)
('NFL', 'SD'): 'team_nfl_lac', # San Diego → Los Angeles Chargers (moved 2017)
('NFL', 'STL'): 'team_nfl_lar', # St. Louis → Los Angeles Rams (moved 2016)
('NFL', 'GNB'): 'team_nfl_gb', # Green Bay alternate
('NFL', 'KAN'): 'team_nfl_kc', # Kansas City alternate
('NFL', 'NWE'): 'team_nfl_ne', # New England alternate
('NFL', 'NOR'): 'team_nfl_no', # New Orleans alternate
('NFL', 'TAM'): 'team_nfl_tb', # Tampa Bay alternate
('NFL', 'SFO'): 'team_nfl_sf', # San Francisco alternate
('NFL', 'WAS'): 'team_nfl_was', # Washington (direct match but include for completeness)
```
These cover:
- Historical relocations (OAK→LV, SD→LAC, STL→LAR)
- Common 3-letter variations used by different data sources
