Release v0.4.4

✨ New Features

🔧 Enhanced User-Agent Payload Testing

• Added -add-ua flag to send payloads via the User-Agent header.
• Works with both GET and POST methods.
• Delta timing logic and replay integration fully supported.
• In POST mode, the first available URL parameter is reused as POST body key – fallback to id if none is found (UA-Mode).

🌟 POST Support Improvements

• Full replay support for POST requests, including:
  • Preserved request bodies
  • Header application
  • Encoding compatibility

📥 Input Validation Improvements

✅ URL Input

• Invalid or malformed URLs from standard input are now gracefully skipped.
• Debug output indicates skipped URLs and reasons.

✅ Payload File

• Input lines now validated and filtered:
  • Empty lines, comments (#), and lines missing {SLEEP} are ignored.
  • Debug logs provide context and line numbers for all ignored lines.

📒 Enhanced Payload Handling

• Payloads containing spaces are auto-encoded unless -encode is set.
• Debug output indicates encoding decisions with before/after values.

🧠 Smarter Output Formatting

• Shared logic for User-Agent and param-based payload reporting (reportFinding) has been simplified and unified.
• Final report includes clearer delta presentation and detection context.

🔢 Debugging Enhancements

• Detailed messages added for:
  • Proxy and replay proxy connectivity checks
  • Request delays (-delay)
  • Payload injections and response timing
  • Payload auto-encoding logic
• Notify debug output now shows truncated messages with coloring.

🔧 Internal Refactors and Fixes

• Introduced recordedRequest struct to support full request replays.
• Abstracted replay logic into a clean doReplayFromRequest() helper.
• Merged duplicated logic between GET and POST flows.
• Added getMethod() utility to avoid manual "GET"/"POST" duplication.
• Final output summary now uses consistent formatting logic.
• Color and prefix constants centralized and fully honored in no-color mode.
• Increased resilience in error handling (nil checks, fallbacks).
• Clean and thread-safe seen map access across goroutines.

🧪 Usage Tips

• Use -debug to trace internal behavior.
• Set -spm to exit early per target on first confirmed delay match.
