Introducing our main agent: Sisyphus (#113)

* docs: rename OmO agent to Sisyphus, OmO-Plan to Planner-Sisyphus

🤖 GENERATED WITH ASSISTANCE OF [OhMyOpenCode](https://github.com/code-yeongyu/oh-my-opencode)

* refactor: rename OmO agent to Sisyphus with automatic config migration

- Rename OmO agent to Sisyphus (uses mythological pushing-the-boulder concept)
- Rename OmO-Plan to Planner-Sisyphus for consistency
- Update config schema: omo_agent → sisyphus_agent
- Add backward compatibility: automatically migrate user's oh-my-opencode.json files
- Migration handles old keys (OmO, omo, OmO-Plan, omo-plan) and rewrites config when detected
- Update agent name mappings, index files, and type definitions
- Add Sisyphus PNG asset to brand identity

* feat(startup-toast): show Sisyphus steering message when enabled

- Updated startup toast to show "Sisyphus on steroids is steering OpenCode" when Sisyphus agent is enabled
- Refactored getToastMessage function to handle conditional message rendering
- Pass isSisyphusEnabled flag from plugin configuration to auto-update-checker hook

* docs(sisyphus): add philosophical context to Sisyphus agent identity

- Add "Why Sisyphus?" explanation connecting the daily work cycle of humans and AI agents
- Emphasize code quality expectations: indistinguishable from senior engineer's work
- Concise identity statement: work, delegate, verify, ship without AI slop

This clarifies the agent's purpose and reinforces the principle that quality code should not reveal whether it was written by human or AI.
