* Remove agentic workflows
The agentic workflows were useful when CCA didn't support loading skills. That's now solved and supported. The agentic workflows come with a couple of issues (limited chars) which make it hard to use. Remove them in favor of the plugin system.
* Remove Agentic Workflows section from README
Removed section about Agentic Workflows from README.
* Remove stale /agentic-workflows references from CONTRIBUTING.md, CODEOWNERS, and docs
