Integrate External Name Generator or Dictionary API

[vkaraujo]

To increase NPC name variety without maintaining a massive YAML list manually, explore integrating an external source for dynamic name generation.
Possible Options:

Fantasy name APIs

    [FantasyNameGenerators.com](https://www.fantasynamegenerators.com/) (not API-based, but scrapeable or replicable)

    [uinames](https://uinames.com/) (deprecated, but others like it exist)

    Open source name datasets on GitHub or datasets from Kaggle

Dictionary APIs

    Datamuse

        E.g., get words with specific sounds or syllables

    [WordsAPI](https://www.wordsapi.com/)

    Random Word API

Public datasets

    GitHub repos with lists of surnames, first names, etc.

    Use Faker gem’s internal name logic

Tasks:

Research and choose a source that fits our fantasy/D&D theme

Add a NpcNameService class that:

    Fetches or generates a name dynamically

    Caches recent names to avoid duplicates (optional)

Update NpcGeneratorService to use this instead of sampling from YAML

Stretch:

Add a fallback to YAML if the API is down

Consider combining with quirky suffixes (e.g., “of the Damp Cavern”)
