fix: correct default weights to sum to 1.0

The default weights were summing to 0.99 instead of 1.0, causing validation errors:
"Default weights must sum to 1.0 (got 0.9900, difference: -0.0100)"

Root cause: Tier distribution was:
- Tier 1: 54% (0.54)
- Tier 2: 27% (0.27)
- Tier 3: 15% (0.15)
- Tier 4:  3% (0.03)
Total: 99% (0.99) ❌

Fix: Increased dependency_security from 0.04 to 0.05
- Tier 1: 55% (0.55)
- Tier 2: 27% (0.27)
- Tier 3: 15% (0.15)
- Tier 4:  3% (0.03)
Total: 100% (1.00) ✅

This permanently fixes the floating-point validation error that appeared frequently in CI.

 # This file defines the default weights for all 23 attributes (updated from 25).
 # Weights are based on tier priority from research report:

-# Tier 1 (Essential):  54% total (5×10% + 1×4%, 6 attributes)
+# Tier 1 (Essential):  55% total (5×10% + 1×5%, 6 attributes)
 # Tier 2 (Critical):   27% total (3% each, 9 attributes)
 # Tier 3 (Important):  15% total (3% each, 5 attributes)
 # Tier 4 (Advanced):    3% total (1% each, 3 attributes)

 # Missing essentials (especially CLAUDE.md at 10%) has 10x impact vs advanced features (1%)

 # Changes in v2.10.0:
-# - Added dependency_security (Tier 1, 4%) - merged dependency_freshness + security_scanning
+# - Added dependency_security (Tier 1, 5%) - merged dependency_freshness + security_scanning
 # - Removed dependency_freshness (merged into dependency_security)
 # - Removed security_scanning (merged into dependency_security)
 # - Removed performance_benchmarks (low ROI)
+# - Fixed weight sum to 1.0 (was 0.99)
