[FEAT] Multilingual Examples

[NeonDaniel]

Objective

Support skill examples in different languages.

Initial Implementation Requirements

• skill.json spec needs to include translated examples (specified in skill.json)
• Core language should be referenced when loading skill data

Other Considerations

• Consider keeping all languages loaded in skill and updating API returns

[NeonDaniel]

Updated skill.json spec specifies metadata should be moved to locale/<lang>/skill.json
