Update Zig to 0.14.1 and add comprehensive build optimization and performance analysis

[Copilot]

This PR updates the Zig MCP server to reference the latest stable Zig version (0.14.1) and significantly enhances it with comprehensive build optimization and performance analysis capabilities.

Updated Documentation Sources

• Changed Zig documentation URLs from /documentation/master/ to /documentation/0.14.1/ to reference the latest stable version
• Ensures users get consistent, stable documentation instead of potentially breaking changes from master

Fixed Outdated Syntax

• Updated @intCast(u8, i) to @intCast(i) in README examples to use modern Zig syntax (changed in Zig 0.11+)
• Added automated detection for outdated cast syntax patterns in code analysis

Comprehensive Build Optimization Features

• Advanced Compiler Flags: Detailed recommendations for -mcpu=native, -flto, -march=native, -fstrip, -funroll-loops, and more
• Build Mode Optimization: Specific guidance for Debug, ReleaseSafe, ReleaseFast, and ReleaseSmall configurations
• Target-Specific Optimization: Cross-compilation and CPU-specific tuning recommendations
• LLVM Backend Integration: Suggestions for LLVM optimization passes and inspection tools

Enhanced Performance Analysis

• SIMD and Vectorization: Detection and recommendations for @Vector operations, SIMD alignment, and parallel processing
• Modern Zig Collections: Analysis for MultiArrayList, BoundedArray, ArrayListUnmanaged, and cache-friendly patterns
• Memory Layout Optimization: Struct packing, alignment analysis, and memory access pattern recommendations
• Builtin Function Detection: Suggestions to use optimized builtins like @sqrt, @sin, @memcpy instead of std library equivalents

Advanced Allocator Analysis

• Comprehensive Allocator Detection: Analysis for Arena, FixedBuffer, GeneralPurpose, Page, and StackFallback allocators
• Memory Strategy Recommendations: Guidance on choosing appropriate allocation patterns for different use cases
• Cleanup Pattern Analysis: Detection of proper defer/errdefer usage and resource management

Security Fix

• Upgraded MCP SDK: Updated @modelcontextprotocol/sdk from version 0.6.0 to 1.25.1
• Resolved Vulnerability: Fixed high-severity DNS rebinding vulnerability (GHSA-w48q-cv73-mx4w)
• Zero Vulnerabilities: No security issues remain in dependencies

Example Enhanced Output

Build Configuration for ReleaseFast:
- Runtime safety checks disabled (-OReleaseFast)
- Maximum LLVM -O3 optimizations
- Enable -march=native for maximum target optimization
- Use -flto for link-time optimization
- Consider -funroll-loops for loop-heavy code

SIMD Optimization Opportunities:
- 3 vector operations detected (SIMD optimization opportunities)
- Consider @Vector for SIMD operations on numeric arrays
- Use @reduce() for efficient vector reductions
- Ensure SIMD vectors are properly aligned for optimal performance

Testing

• ✅ All 13 validation checks pass
• ✅ All 4 tools functional and tested
• ✅ Build successful with updated SDK
• ✅ Integration tests with real-world Zig code validated
• ✅ No breaking changes from dependency upgrade

The server now serves as a comprehensive Zig development assistant, providing detailed build optimization guidance and performance analysis that helps developers write faster, more efficient Zig code using modern language features and best practices.
