=== FIX (task 27): info.d unsigned indexOf wrap ===
Bug: src/tofu/commands/info.d:93 — `size_t pos = content.indexOf("deps")`.
indexOf returns ptrdiff_t (-1 for not found); unsigned size_t wraps -1 to
SIZE_MAX, making `if (pos < 0)` a no-op → ArrayIndexError on recipes
without a deps field (uncaught D Error, crashed -Si).

Fix applied:
  1. scanDepsArray: size_t pos → ptrdiff_t pos (+ explanatory comment).
  2. Added regression unittest (Test 4): cached recipe WITHOUT deps field
     (name/ver/summary/build_system only) → infoCommand returns 0.
     Recipe written via existing writeRecipe helper, mirrors Test 3 pattern.

Audit of same pattern elsewhere (checked, NOT bugs):
  - info.d:36  auto kp = ...indexOf(key)          → auto infers ptrdiff_t ✓
  - recipeparse.d:52,112 auto idx = indexOf(...)  → ptrdiff_t ✓
  - fetch.d:82  auto idx = indexOf(...)           → ptrdiff_t ✓
  - search.d / remove.d / install.d               → inline >= 0 / == -1 ✓
  No other unsigned indexOf assignment found.

Verification:
  dub build  → Linking tofu (pass)
  dub test   → 23 modules passed unittests
  smoketest  → PASS: 16 checks passed, All checks passed.
