A few of the doc blocks in this file had drifted from what the code
actually does:
- inboundTransports' rule list claimed tunnel reads settings.network
the same as shadowsocks. It doesn't — tunnel uses
settings.allowedNetwork (3x-ui's wrapper around dokodemo-door).
- The "merge" hint above the settings-parsing block undersold what
happens: SS / Tunnel override the streamSettings-derived bit while
Mixed adds to it.
- portConflictDetail's example message and the checkPortConflict
intro still mentioned "the old port-only check", a historical
comparison that no longer says anything useful now that the
transport-aware check is the only one.
- transportTagSuffix was documented as a generateInboundTag helper,
but it's now also called by the conflict-error formatter.
Tighten the wording so future readers don't have to cross-check the
code against the doc.
