fix(tsc): preserve informational output

[amandeavor]

Summary

• pass TypeScript informational invocations through without diagnostic filtering
• preserve native output for config, file listings, initialization, help, and version commands
• keep normal typecheck invocations on the compact diagnostic path
• retain the existing npx tsc fallback when tsc is not installed directly

Closes #3750

Tests

• added coverage for every informational flag
• added coverage that regular --noEmit and project typechecks remain filtered
• cargo fmt --all --check
• cargo clippy --all-targets
• cargo test --all -- --test-threads=1
