🔧 Add Conditional Compilation for Different Targets

🔧 Add Conditional Compilation for Different Targets

Issue Description

Performance analysis found that the current build includes all features and dependencies for all targets, leading to larger binaries and suboptimal performance for specific deployment scenarios.

📍 Problem Areas

• All features compiled regardless of target needs
• Large binary sizes due to unused dependencies
• Suboptimal performance for specific use cases
• Missing target-specific optimizations

🎯 Solution Approach

Implement conditional compilation with feature flags and target-specific optimizations for different deployment scenarios.

📋 Implementation Tasks

• Add feature flags for optional functionality
• Implement target-specific compilation
• Optimize dependencies per target
• Add build profiles for different deployment scenarios
• Implement conditional feature loading

📊 Expected Performance Improvements

• Binary size: 30-40% reduction for minimal deployments
• Startup time: Faster initialization for targeted builds
• Memory usage: Reduced footprint for specific use cases
• Build time: Faster compilation for targeted features

Estimated Effort: 2-3 days
Priority: Lower (Build optimization)

No files, tests, or entry points are named. Start by locating the Rust build and dependency configuration, then map the deployment targets and optional functionality before deciding how feature flags, target-specific compilation, and build profiles should be organized. Done means targeted builds reduce unused dependencies and meet the stated binary-size, startup, memory, and build-time goals.
