Normalize agent instructions and workplan frontmatter (STATE-WP-0067)

- Align agent files with on-disk workplan prefixes (infer from workplan ids)
- Set workplan domain to registered domain_slug; add topic_slug where applicable
- Repair frontmatter delimiter formatting; migrate legacy task status literals
- Regenerate AGENTS.md, CLAUDE.md, and .claude/rules from State Hub templates

+
+## One-liner
+
+**Mission control for Kubernetes hosts, exposed to LLM agents through MCP.**.
+
+## Core Idea
+
+tele-mcp exists to provide the capability described in INTENT.md.
+
+## In Scope
+
+- Maintain the repository's primary implementation.
+- Keep docs, tests, and operational metadata current.
+
+## Out of Scope
+
+- Own unrelated adjacent systems.
+- Make irreversible operational decisions without human approval.
+
+## Current State
+
+- Status: active; implementation and stability should be verified by the repo agent.
+
+## Getting Oriented
+
+- Start with: INTENT.md
+- Agent instructions: AGENTS.md
+- Workplans: workplans/
