v0.4.0 - Least Time & Session Sticky Load Balancing

v0.4.0 - Least Time & Session Sticky Load Balancing

Added

Load Balancing

• Least Time balancer: EWMA-based least response time algorithm, automatically selects the fastest upstream
• Session Sticky balancer: Cookie-based session affinity with consistent hash sharding, supporting Cookie expiration, domain, path, Secure/HttpOnly/SameSite attributes
• YAML configuration support: least_time, sticky strategies and parameters

Platform

• FreeBSD deployment examples

Fixed

• Least Time response time recording correction
• Sticky Cookie format, shard key, and expiration check fixes
• Sticky double-stop protection and restart support
• Config validation: least_time default_time must not be negative

Tests

• Least Time and Sticky balancer integration tests
• Least Time and Sticky benchmarks
