docs: fix agent name casing in documentation (#117)

* docs: fix agent name casing in documentation

- Update all instances of 'openagent' to 'OpenAgent'
- Update all instances of 'opencoder' to 'OpenCoder'
- Fixes #115: --agent flag is case-sensitive

The --agent flag requires capitalized agent names (OpenAgent, OpenCoder)
but documentation showed lowercase versions, causing confusion for users.
Updated README.md and all docs/ files to use correct casing.

* refactor: migrate from grok-code to big-pickle model

- Remove model specification from contextscout.md subagent
- Update eval YAML files to use opencode/big-pickle
- Update documentation to reference big-pickle as default
- Fixes compatibility as grok-code-fast is no longer available

- .opencode/agent/subagents/core/contextscout.md

- evals/agents/shared/tests/golden/02-delegation-test.yaml

 ## Common Questions
 
 **Q: What's the main way to use this?**  
-A: Use `opencode --agent openagent` as your default for general tasks and questions. For complex multi-file coding work, use `opencode --agent opencoder`. Both coordinate with specialists as needed.
