refactor(codeagent-wrapper): remove sisyphus agent and unused code

- Remove sisyphus agent from default config (references deleted sisyphus.md)
- Clean up unused variables: useASCIIMode, jsonMarshal
- Remove unused type: codexHeader
- Remove unused functions: extractMessageSummary, extractKeyOutput, extractTaskBlock
- Update tests to reflect 6 default agents instead of 7
