pokemon/cosmoem omits splash, and the docs do not explain whether retained pre-evolution moves are excluded

[Mygod]

/api/v2/pokemon/cosmog includes splash, but /api/v2/pokemon/cosmoem does not.

This seems incorrect, or at least under-documented, because Cosmoem can legally retain Splash when evolved from Cosmog.

I checked the current documentation for the pokemon endpoint and move learn methods, and I could not find anything stating that /pokemon/{id} is intended to exclude retained pre-evolution moves.

Steps to Reproduce:

1. Request https://pokeapi.co/api/v2/pokemon/cosmog
2. Observe that moves includes splash
3. Request https://pokeapi.co/api/v2/pokemon/cosmoem
4. Observe that moves does not include splash

Current behavior:

• cosmog includes teleport and splash
• cosmoem includes teleport and cosmic-power
• cosmoem has no splash entry at all

Expected behavior:

One of these should be true:

• cosmoem should include splash, since a Cosmoem can legally have that move after evolving from Cosmog
• or the docs should explicitly state that /pokemon/{id} only includes direct learnset entries and excludes retained pre-evolution moves

Without that clarification, this currently looks like missing move data.
