refactor: rename builder_enabled to default_builder_enabled and remove replace_build (#251)

- Renamed sisyphus_agent.builder_enabled to default_builder_enabled for clarity
- Removed sisyphus_agent.replace_build option entirely
- Default build agent is now always demoted to subagent mode when Sisyphus is enabled
- Updated schema and regenerated JSON schema
- Updated all documentation (EN, KO, JA, ZH-CN)

BREAKING CHANGE: Configuration migration required for users using builder_enabled or replace_build options.

Closes #250
