v1.13.1

Added

• Comprehensive inline documentation for configuration constants - Added detailed comments explaining provider
  defaults, metadata, environment variables, and performance configuration constants to improve code maintainability

Refactored

• Background process tracking - Improved cleanup mechanism with CLAUVER_BG_PIDS array for explicit PID tracking:
  • Added track_background_pid function for centralized PID tracking
  • Implemented SIGTERM signal for graceful shutdown before SIGKILL
  • Added wait command to ensure proper process termination
  • Improved PID validation and removed unnecessary upper bound check
  • Track test PIDs in cmd_test function for better cleanup
• Installation detection - Simplified install.sh method detection by removing temp file approach
• Provider matching - Simplified regex pattern matching in cmd_reset_provider for built-in providers
• API key validation - Removed strict format checks, length requirements, and character restrictions for increased
  flexibility across different provider key formats
• Logging functions - Removed duplicate standalone log, success, warn, and error functions in favor of prefixed
  UI module versions (ui_log, ui_success, ui_warn, ui_error)
• Setup command - Removed ASCII art banner for cleaner output

Changed

• Test API key patterns - Normalized test API key patterns across all test suites for consistency
• Removed unused MIN_API_KEY_LENGTH validation constant

Removed

• Redundant logging functions - Dropped standalone logging functions, now using prefixed UI module versions exclusively
