Remove all user-facing references to the internal `legacyDNSMode` variable
name. Error messages now reuse the deprecated.Note.MessageWithLink() method
to provide consistent deprecation text with migration URLs. Other internal
jargon ("consume response state", "response_*") is replaced with
user-friendly descriptions.
Add two migration guide entries under 1.14.0: one for strategy → rule items,
one for address filter fields → evaluate with match_response.
For historical reasons, sing-box's `domain_suffix` rule matches literal prefixes instead of the same as other projects.
This change modifies the behavior of `domain_suffix`: If the rule value is prefixed with `.`,
the behavior is unchanged, otherwise it matches `(domain|.+\.domain)` instead.
The `process_path` rule of sing-box is inherited from Clash,
the original code uses the local system's path format (e.g. `\Device\HarddiskVolume1\folder\program.exe`),
but when the device has multiple disks, the HarddiskVolume serial number is not stable.
This change make QueryFullProcessImageNameW output a Win32 path (such as `C:\folder\program.exe`),
which will disrupt the existing `process_path` use cases in Windows.
