feat(workflows): adaptive context enrichment for 1M models

 When `USE_WORKTREES` is `false`, all executor agents run without `isolation="worktree"` — they execute sequentially on the main working tree instead of in parallel worktrees.
 
+Read context window size for adaptive prompt enrichment:
+
+```bash
+CONTEXT_WINDOW=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" config-get context_window 2>/dev/null || echo "200000")
+```
+
+When `CONTEXT_WINDOW >= 500000` (1M-class models), subagent prompts include richer context:
+- Executor agents receive prior wave SUMMARY.md files and the phase CONTEXT.md/RESEARCH.md
+- Verifier agents receive all PLAN.md, SUMMARY.md, CONTEXT.md files plus REQUIREMENTS.md
+- This enables cross-phase awareness and history-aware verification
+
 **If `phase_found` is false:** Error — phase directory not found.
 **If `plan_count` is 0:** Error — no plans found in phase.
 **If `state_exists` is false but `.planning/` exists:** Offer reconstruct or continue.
