Step 330: Review Gates (12/12 tests)

Browse Source 
Configurable auto-approve rules for review gate. Default policy auto-approves
deterministic/template with >=0.9 confidence. @Review(required) always
overrides. Policy serialization, wildcard rules, and 2 new MCP tools.

### Step 330: Review Gates
**Status:** PASS (12/12 tests)
Configurable auto-approve rules and review queue. Default policy auto-approves
deterministic/template workers with >=0.9 confidence; everything else requires
review. Explicit @Review(required) always overrides auto-approve.
**Files created:**

- `editor/tests/step330_test.cpp` — 12 tests: deterministic/template auto-approve,
LLM requires review, low confidence rejected, custom policy, default policy,
@Review override, wildcard rule, policy roundtrip, empty policy, default
require-review, human requires review
