- 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

* fix: show error messages when oh-my-opencode.json config fails to load
- Add console.error output for config parse errors (syntax errors)
- Add console.error output for config validation errors (schema violations)
- Display helpful hints for JSON syntax errors
- List all validation errors clearly with proper formatting
- Errors now shown immediately regardless of hook configuration
Fixes#241
* refactor: replace console.error with toast notifications for config errors
- Replace console.error with ctx.client.tui.showToast() for better UX
- Show toast notifications for both syntax errors and validation errors
- Toast notifications persist for 10 seconds for visibility
- Display error details with bullet points for validation errors
- Include helpful hints for JSON syntax errors
This provides a more user-friendly notification system that integrates
with OpenCode's UI instead of just logging to console.

Previously, the condition '&&plannerEnabled&&replacePlan' caused agents to be
completely removed instead of demoted to subagent mode. The logic incorrectly
prevented agents from being added back as subagents when Sisyphus is enabled
with default config.
Fixed by simplifying to just 'replacePlan' condition - agents are now properly
demoted to subagent mode when replacement is enabled, which is the intended
behavior per the README.

- Renamed agent from 'Builder-Sisyphus' to 'OpenCode-Builder' in schema and config
- Removed BUILD_SYSTEM_PROMPT and BUILD_PERMISSION custom overrides

- Filter out original 'build' and 'plan' agents when Builder-Sisyphus/Planner-Sisyphus are enabled with replacement
- Previously both agents could coexist even with replace_build/replace_plan: true
- Now only the replacement agent exists when both enabled and replacement flags are true
- Maintains backward compatibility for all configuration combinations
Fixes#231
Detects non-interactive environments (CI, opencode run) and prevents session idle when:
- Background tasks are still running
- Incomplete todos remain in the queue
Changes:
- Add isNonInteractive() detector for CI/headless environment detection
- Export detector from non-interactive-env hook module
- Enhance todo-continuation-enforcer to inject prompts BEFORE session.idle
- Pass BackgroundManager to todo-continuation-enforcer for task status checks
This fix prevents `opencode run` from exiting prematurely when work is pending.
