fix: resolve #192 — move dead code to docs/reference, fix GENOME.md

- game/npc-logic.js → docs/reference/npc-logic-prototype.js (ES module, never imported)
- scripts/guardrails.js → docs/reference/guardrails-prototype.js (HP/MP validation, wrong game)
- Updated GENOME.md architecture diagram to reflect actual file structure
- Updated DEAD_CODE_AUDIT to mark these as resolved
- Corrected JS line counts (6,033 across 11 files)
- Removed empty game/ directory

The actual CI scripts (guardrails.sh, smoke.mjs) remain active in scripts/.

-### Potentially Unimported Files
+### Dead Code — Resolved (2026-04-15, Issue #192)
 
-The following files were added by recent PRs but may not be imported
-by the main game runtime (`js/main.js` → `js/engine.js`):
+The following files were confirmed dead code — never imported by any runtime module.
+They have been moved to `docs/reference/` as prototype reference code.
 
-| File | Added By | Lines | Status |
-|------|----------|-------|--------|
-| `game/npc-logic.js` | PR #79 (GOFAI NPC State Machine) | ~150 | **Verify import** |
-| `scripts/guardrails.js` | PR #80 (GOFAI Symbolic Guardrails) | ~120 | **Verify import** |
-
-**Action:** Check if `js/main.js` or `js/engine.js` imports from `game/` or `scripts/`.
-If not, these files are dead code and should either be:
-1. Imported and wired into the game loop, or
-2. Moved to `docs/` as reference implementations
+| File | Original | Resolution |
+|------|----------|------------|
+| `game/npc-logic.js` | PR #79 (GOFAI NPC State Machine) | **Moved to `docs/reference/npc-logic-prototype.js`** — ES module using `export default`, incompatible with the global-script loading pattern. Concept (NPC state machine) is sound but not wired into any game system. |
+| `scripts/guardrails.js` | PR #80 (GOFAI Symbolic Guardrails) | **Moved to `docs/reference/guardrails-prototype.js`** — validates HP/MP/stats concepts that don't exist in The Beacon's resource system. The `scripts/guardrails.sh` (bash CI script) remains active. |
