docs(skills): update and standardize skill versions to 2.0.0 in frontmatter

- Bump version to 2.0.0 across all 8 multi-agent-mux skills reflecting A-4 Phase 2 adapter architecture and Option B isolation deprecation.
- Standardize author (godopu), license (MIT), platforms, environments, and metadata blocks across all SKILL.md files.

Always creates a herdr session — never backgrounds with nohup/disown. Writes the new session to .mam/agent-sessions.yaml. Use when you want to start a fresh agent (no prior UUID) for a new project workspace."

 description: "Run a long-lived reconciler that watches .mam/agent-sessions.yaml against the actual herdr/agent runtime state and reconciles them. Use when you want live visibility into which agent sessions are running, which are dead, which have stale YAML entries, and which have new session ids that haven't been recorded yet. Runs as a persistent loop (`reconcile.sh --subscribe`) that keeps going until it times out, idles out, or is interrupted."
