Added
- Welcome message config now uses ``welcome-message.delay-seconds``
- Nametag privacy adds nametag-privacy.visibility per relation (same-clan, enemy-clan, no-clan) with values always/hideforotherteams/hideforownteam/never.
- Configurable bypass permission nametag-privacy.bypass-permission (default vanguardclans.bypass.nametag) lets holders see all nametags and skip the plugin scoreboard.

Bug Fix

- Welcome delay config mismatch: code read welcome-message.delay-seconds while config shipped delay-ticks; legacy ticks now auto-convert, seconds are the main key.
- Nametag granularity: previously just hide/reset with no per-relation control and no configurable bypass permission; now visibility is per relation (same/enemy/no-clan) and bypass permission is configurable.
