Log Message:
syncduke: add UTF-8 text tiers (quadrant/sextant) + charset detection

SyncDuke's block-character fallback tiers were hardcoded to CP437, so the
Unicode quadrant/sextant tiers (already in the enum + renderer) were never
offered and the block tiers never emitted native Unicode. Detect the client
charset from Synchronet's <node>/terminal.ini (chars=), reachable via $SBBSNODE
even under the lobby launch, and thread it into rt_config: block tiers emit
native UTF-8 on a UTF-8 terminal (CP437 bytes otherwise), and the quadrant/
sextant tiers join the F4 cycle only when the client is UTF-8.

Charset precedence, highest first: -charset utf8|cp437|auto command-line arg
(for non-Synchronet DOOR32.SYS installs with no terminal.ini), syncduke.ini
[video] charset, then terminal.ini auto-detect, else CP437. Mirrors SyncDOOM,
which relies on the door running Translate-Character-Set-No (XTRN_BIN) so its
output reaches the terminal untranslated. Documents both in the README and
syncduke.example.ini.
