Added

• Provides error when config is explicitly specified but not found.

Fixes

• Adaptive indentation for define blocks matches the indentation style within each block (Issue #24).
• Centralized define block tracking, error formatting, and standard rule processing into utility functions.
• Added support for Make patterns: $< $@, $^ $@, command $@.
• Improved file vs. phony target identification (Issue #23).
  • Avoids assumptions (e.g., removing hard-coded extensions).
  • Variable references (e.g., $(foo)) are not incorrectly marked as .PHONY.
• Avoids comment interference when parsing (Issue #24).
• Avoids false positives for duplicate targets when including comment-only targets.
• Versioning check correctly identifies post releases as new versions.
