Code Review

This pull request adds IPv6 support by configuring IPv6 DNS servers and routing in XrayBaseService, updating the DNS query strategy in AbstractConfigParser, and adding IPv4/IPv6 addresses to the tun2socks configuration. It also adds LeakCanary as a debug dependency. The review feedback recommends wrapping the IPv6 DNS server registration in a try-catch block to prevent crashes from invalid user input, and centralizing the LeakCanary dependency version within the Version Catalog.

Adding DNS servers directly from user-configured settings without validation can cause the application to crash if an invalid IPv6 address is entered. VpnService.Builder.addDnsServer throws an IllegalArgumentException for malformed addresses. Wrapping the call in a try-catch block ensures the service remains robust and doesn't crash due to invalid user input.

        if (settings.ipV6Enable) {
            val dnsV6Servers = settings.dnsIPv6.split(",").filter { it.isNotBlank() }
            dnsV6Servers.forEach {
                try {
                    builder.addDnsServer(it.trim())
                } catch (e: IllegalArgumentException) {
                    Log.e(TAG, "Invalid IPv6 DNS server: $it", e)
                }
            }
        }

To maintain consistency and centralized dependency management, avoid hardcoding dependency versions directly in build.gradle.kts. Instead, define the LeakCanary dependency in the Version Catalog (gradle/libs.versions.toml) and reference it here.
