fix(settings): preserve raw Match Voice Chat semantics

[e54-bot]

Summary

• Reconcile Match Voice Chat onto the canonical lobby.enableMatchVoiceChat boolean setting.
• Preserve the reviewed Enabled raw Workshop value family, including 启用 in zh-CN.
• Reject the unevidenced false/Disabled state explicitly instead of inferring a mapping.
• Add projection reconciliation, census support, and en-US/zh-CN parser-emitter regressions.

Validation

• cargo fmt --all -- --check
• cargo clippy --workspace --all-targets -- -D warnings
• cargo test --workspace --all-targets — 287 passed
• cargo run --locked -p workshop-rs --bin workshop-catalog-gen -- check
• Independent generic-Bool ablation makes the enabled regression fail at Enabled parsing.

Remaining integration evidence

The Wright provider en-US/zh-CN end-to-end workflows from #245 still need to consume a released workshop-rs version containing this fix before that acceptance evidence can be claimed.

Refs #144

[Teakowa]

crates/workshop-rs/src/settings/table.rs / tests/settings_pipeline.rs: the patch encodes matchVoiceChat -> disabled -> Disabled (and zh-CN 禁用) as a stable contract, but the reviewed locale corpus only links enableMatchVoiceChat directly to Enabled; its Disabled provenance is from unrelated settings. #144 explicitly requires the disabled state to be independently evidenced rather than inferred by symmetry. The new round-trip test exercises the mapping introduced by this same patch, so it does not supply independent evidence. Please add provenance-linked Workshop/upstream evidence that enableMatchVoiceChat: false uses raw Match Voice Chat: Disabled / 比赛语音聊天: 禁用, or do not encode that false-state mapping yet.
