Tom Boucher bb27263def fix(#913): guard top-level Claude Code plan-phase against role collapse (#915)
Three-part fix for the top-level inline collapse bug:

1. plan-phase.md: add <runtime_compatibility> block after
   </available_agent_types> that makes the Agent-availability
   requirement explicit; workflow fails-closed (stops with a clear
   log) in genuinely Agent-less contexts.

2. plan-phase.md: rename 7 "ORCHESTRATOR RULE — CODEX RUNTIME"
   labels to "ALL RUNTIMES" so the spawn guard applies universally
   (not just when Codex is detected).

3. execute-phase.md: scope the existing "Other runtimes" inline-
   fallback prose to non-Claude contexts, preserving the #853
   backgrounded-agent behaviour for Claude Code background agents.

Fixed 913

Top-level Claude Code /gsd-plan-phase now always spawns the researcher/planner/plan-checker agents instead of collapsing them inline — a <runtime_compatibility> block after </available_agent_types> makes the Agent-availability requirement explicit and documents that the workflow fails-closed (stops with a clear log message) in genuinely Agent-less contexts; seven "ORCHESTRATOR RULE — CODEX RUNTIME" labels are renamed to "ALL RUNTIMES" so the guard applies universally; execute-phase.md scopes its existing "Other runtimes" inline-fallback prose to non-Claude contexts, preserving the #853 backgrounded-agent behaviour.
