DbtQuoting -> ResolvedQuoting conversion

Error message

DbtQuoting -> ResolvedQuoting conversion

What it means

Panic "DbtQuoting -> ResolvedQuoting conversion" occurs in NodeBaseAttributes for seeds when `properties_config.quoting.try_into::<ResolvedQuoting>()` returns Err. Like the model case, this conversion should be total; failure signals an unexpected field/value combination in the seed's quoting config.

Solutions

1. Update the TryFrom<DbtQuoting> for ResolvedQuoting impl to cover the failing field/variant.
2. Normalize or drop unsupported quoting keys for seeds before conversion.
3. Propagate the error with seed name context instead of expect.

Example fix

// before
quoting: properties_config.quoting.try_into().expect("DbtQuoting -> ResolvedQuoting conversion"),
// after
quoting: properties_config.quoting.clone().try_into().unwrap_or_default(),

let rq: Result<ResolvedQuoting, _> = properties_config.quoting.clone().try_into();
if rq.is_err() { eprintln!("seed quoting not convertible: {:?}", properties_config.quoting); }

fn convertible_seed_quoting(q: &DbtQuoting) -> bool { ResolvedQuoting::try_from(q.clone()).is_ok() }

let quoting: ResolvedQuoting = properties_config.quoting.clone().try_into().unwrap_or_default();

When it happens

Trigger: Building NodeBaseAttributes for a seed whose properties_config.quoting carries a value the TryFrom impl cannot map (e.g., a newly added DbtQuoting field or an incompatible enum variant).

Common situations: Seed YAML with quoting keys that the parser's ResolvedQuoting type doesn't support; version drift where DbtQuoting gained fields before the conversion was updated.
