Review locale integration

As a developer and maintainer it would a general improvement to expose and allow locales for the various strings that are used for logging and markdown display.

Acceptance criteria

• Review viability and effort ONLY, this is not an implementation issue

  • review viability of server locale settings being processed from host
    • this should account for any locale the llm/model my be running in
  • review a cli and programmatic locale override for scenarios we can't foresee
  • review available packages

Assumptions and questions

• Our doc resources are primarily en-US this may end up being easier referencing a standalone translation mcp outside of this work

• Since we have to compile the server having the locales compiled alongside or within our dist is feasible

• A standalone directory, or underneath src, containing some level of JSON, sans TypeScript might work, but it would be a developer-nice to having Typing annotations pop up for the string identifiers instead of having to reference the files.

• Server logs would be easier if we migrated towards "codes" vs burning cycles on "admin locale"
