Restrict workflow permissions to contents: read

All CI jobs and the deploy workflow only need to read repo contents.
Adding explicit top-level permissions satisfies zizmor's
excessive-permissions audit.

 The existing seed data has curated route ordering and normalized route names (from beans r48e, qvww, j28y) that must be preserved — only encounter condition data should be added/changed.
 
-## Reference branch
-
-**Branch:** \`feature/encounter-conditions\` (PoC)
-
-Key changes on the PoC branch:
-- **Backend model:** \`RouteEncounter\` gains a \`condition\` field (String(30), default \`""\`)
-- **Migration:** \`c0d1e2f3a4_add_condition_to_route_encounters.py\` — adds condition column + updated unique constraint
-- **Seed loader:** handles \`conditions\` dict format: \`{"morning": 50, "day": 20, "night": 0}\` per encounter
-- **API/schema:** \`condition\` field exposed in route encounter responses
-- **Frontend types:** \`RouteEncounter\` type gains \`condition: string\`
-- **Frontend UI:** condition selector tabs and badges in \`RunEncounters\` and \`EncounterModal\`
-
-## Seed data format
-
-When an encounter has per-condition rates, the JSON uses a \`conditions\` dict instead of a flat \`encounter_rate\`:
-
-\`\`\`json
-{
-  "pokeapi_id": 163,
-  "pokemon_name": "Hoothoot",
-  "method": "walk",
-  "encounter_rate": null,
-  "conditions": {
-    "night": 50,
-    "morning": 10,
-    "day": 0
-  },
-  "min_level": 2,
-  "max_level": 5
-}
-\`\`\`
-
-For encounters without variant rates, the existing flat \`encounter_rate\` field remains unchanged.
-
-## Approach
-
-### Phase 1: HeartGold (reference game)
-
-Create complete encounter condition data for HeartGold first. This serves as the reference implementation and validates the full pipeline (seed → DB → API → UI).
-
-HeartGold uses **morning/day/night** conditions for walking encounters. Source: PokeDB data (the import tool at \`tools/import-pokedb\` already has the raw per-condition rates, but \`extract_encounter_rate()\` currently flattens them to \`max()\`).
-
-### Phase 2: All other games with conditions
-
-Update the remaining games' seed data with encounter conditions, without changing route order or route names. Match encounters by route name + Pokémon + method and add the \`conditions\` dict.
-
-## Condition types by game group
-
-- **morning/day/night**: Gold, Silver, Crystal, HeartGold, SoulSilver, Diamond, Pearl, Platinum, Brilliant Diamond, Shining Pearl
-- **spring/summer/autumn/winter**: Black, White, Black 2, White 2
-- **weather (clear, overcast, rain, thunderstorm, snow, snowstorm, sandstorm, intense-sun, heavy-rain, fog)**: Sword, Shield
-- **SOS calls**: Sun, Moon, Ultra Sun, Ultra Moon
-- **No conditions (flat rates)**: Red, Blue, Yellow, Ruby, Sapphire, Emerald, FireRed, LeafGreen, X, Y, Omega Ruby, Alpha Sapphire, Let's Go Pikachu, Let's Go Eevee, Legends: Arceus, Scarlet, Violet, Legends: Z-A

 ## Checklist
 
 ### Infrastructure (merge from PoC)
-- [ ] Merge backend model + migration for \`condition\` field on \`RouteEncounter\`
-- [ ] Merge seed loader changes to handle \`conditions\` dict format
-- [ ] Merge API/schema changes to expose \`condition\` field
-- [ ] Merge frontend type updates (\`RouteEncounter.condition\`)
-- [ ] Merge frontend UI (condition selector tabs/badges in RunEncounters & EncounterModal)
+- [x] Merge backend model + migration for `condition` field on `RouteEncounter`
+- [x] Merge seed loader changes to handle `conditions` dict format
+- [x] Merge API/schema changes to expose `condition` field
+- [x] Merge frontend type updates (`RouteEncounter.condition`)

-### Phase 1: HeartGold
-- [ ] Update \`tools/import-pokedb\` to extract per-condition rates instead of flattening to \`max()\`
-- [ ] Write a merge script that adds condition data to existing seed files without touching route names/order
-- [ ] Generate and merge condition data for HeartGold
-- [ ] Verify HeartGold seed data loads correctly and conditions display in the frontend
+### Import tool updates
+- [x] Update `tools/import-pokedb` to extract per-condition rates instead of flattening to `max()`
+- [x] Fix encounter method mappings (horde, SOS as distinct methods)
+- [x] Write merge script (`tools/merge-conditions.py`)
 
-### Phase 2: Remaining games
-- [ ] Gen 2: Gold, Silver, Crystal (morning/day/night)
-- [ ] Gen 4: SoulSilver, Diamond, Pearl, Platinum, Brilliant Diamond, Shining Pearl (morning/day/night)
-- [ ] Gen 5: Black, White, Black 2, White 2 (spring/summer/autumn/winter)
-- [ ] Gen 7: Sun, Moon, Ultra Sun, Ultra Moon (SOS calls)
-- [ ] Gen 8: Sword, Shield (weather conditions)
-- [ ] Verify all updated games load correctly and show conditions in the UI

+- [x] Gen 8: Sword, Shield (weather conditions)
+- [x] Verify all hooks pass (`prek run --all-files`)
 
-## Success criteria
-
-All games that have condition-dependent encounters show those conditions in the UI, so players can see what they can actually catch given their current game state (time of day, season, weather, etc.).
