48639942f6 style: run gofmt across entire codebase
330 non-vendor files had minor formatting inconsistencies
(comment alignment, whitespace). No logic changes.

f640cfee27 fix: log SJIS decoding errors instead of silently discarding them
Add SJISToUTF8Lossy() that wraps SJISToUTF8() and logs decode errors at
slog.Debug level. Replace all 31 call sites across 17 files that previously
discarded the error with `_, _ =`. This makes garbled text from malformed
SJIS client data debuggable without adding noise at default log levels.

d32e77efba refactor: replace panic calls with structured error handling
Replace ~25 panic() calls in non-fatal code paths with proper
s.logger.Error + return patterns. Panics in handler code crashed
goroutines (caught by defer/recover but still disruptive) instead
of failing gracefully.

Key changes:
- SJISToUTF8 now returns (string, error); all 30+ callers updated
- Handler DB/IO panics replaced with log + return/ack fail
- Unhandled switch-case panics replaced with logger.Error
- Sign server Accept() panic replaced with log + continue
- Dead unreachable panic in guild_model.go removed
- deltacomp patch error logs and returns partial data

Panics intentionally kept: ByteFrame sentinel, unimplemented
packet stubs, os.Exit in main.go.

9b69564c49 fix: prevent server crash on unsupported Shift-JIS characters (#116)
UTF8ToSJIS panicked when encountering characters outside the Shift-JIS
range (emoji, Lenny faces, cuneiform, etc.), crashing the server when
such characters were sent via the Discord relay channel.

Replace the panic with graceful filtering that drops unmappable runes
and preserves valid content. Also fix ToNGWord index-out-of-range panic
on empty encoder output.

Closes #116
