v2.16.3 — Windows Fix + Auto-Mode Safety

Windows Path Fix

• normalize_tool_path() auto-converts MSYS2/Git Bash paths (/c/Users/...) to native format
• Centralized normalization for all 14 tools + cache keys

Auto-Mode Safety

• task mode no longer auto-selected (broke edits by reordering lines)
• Compressed outputs include hint: [compressed — use mode="full" for complete source]
• Raised heuristic thresholds (map at 3k+, no auto-signatures for code)

full Mode Integrity

• Removed silent task filter on full mode
• full no longer degrades to aggressive after idle
