"""ORCH-074 (G1): the dead `model:` frontmatter is gone from all 6 agent prompts.

launcher.py never reads frontmatter `model:` — it was a lying/dead declaration
(claude-sonnet-4-6 / claude-opus-4-7) that contradicted the real model resolved
from config (ORCH-41). The mine: if someone "fixed" the launcher to read it, every
agent would silently fall back to a stale model. G1 removes the line entirely so
config (agent_model_*) stays the single source of truth.

TC-01: no .openclaw/agents/*.md contains a `^model:` line in its frontmatter.
TC-02: each frontmatter is still valid YAML and keeps name/description.
