fix: respect LOG_URLS=false to disable request URL logging

[aayushprsingh]

Summary

Fixes LOG_URLS=false not disabling request URL logging.

Problem: The logging middleware in cmd/main.go only checked NOLOGS=true to suppress logs. Setting LOG_URLS=false (as the user in #78 attempted) was completely ignored — all request paths (GET /https://...) were still logged.

Root cause: The middleware condition in cmd/main.go was:

if os.Getenv("NOLOGS") != "true" {

This meant only NOLOGS=true could disable logging. LOG_URLS was only checked later in handlers/proxy.go for verbose modified-URL logging.

Fix: Added && os.Getenv("LOG_URLS") != "false" to the condition:

if os.Getenv("NOLOGS") != "true" && os.Getenv("LOG_URLS") != "false" {

Behaviour:

LOG_URLS	NOLOGS	Result
unset	not "true"	URLs logged (backward compatible default)
true	not "true"	URLs logged + verbose modified-URL logs
false	*	No URL logging

Fixes #78
