Add inline-union support and complete pdaSeed generation

[lorisleiva]

This PR introduces an INLINE_UNIONS allowlist in the generator so that unions without a registered<Name> twin can be emitted on an opt-in basis, with a per-union stripSuffix controlling variant naming. The infrastructure is validated end to end by completing pdaSeed, which was deliberately left out of the previous PR pending exactly this machinery. The pdaSeed category now joins count, discriminator, and link under CATEGORY_ROUTING, and codama-nodes/src/generated/pda_seed_nodes/ gains five files: per-node constant_pda_seed_node.rs and variable_pda_seed_node.rs, the inline-union constant_pda_seed_value.rs, the category-union pda_seed_node.rs, and a mod.rs. The hand-written pda_seed_nodes/*.rs files shrink to constructors and #[cfg(test)] mod tests blocks, mirroring the PR #1/#2 treatment of link and count/discriminator nodes. One bespoke impl From<ValueNode> for ConstantPdaSeedValue is added to the hand-written constant_pda_seed_node.rs to bridge the broader ValueNode enum into the new ConstantPdaSeedValue superset that includes ProgramId(ProgramIdValueNode). The ConstantPdaSeedNode.value field type changes from ValueNode to ConstantPdaSeedValue; existing call sites that pass leaf value nodes work via the auto-derived From<Variant> impls, and the one caller in codama-korok-visitors/src/set_pdas_visitor.rs that passes a resolved ValueNode flows through the new bridge.

Also lands the box-all-union heuristic: every direct (non-Vec) field whose type is a union is wrapped in Box<\u2026> (required \u2192 Box<T>; optional \u2192 Box<Option<T>>, box outside Option). This keeps every category-union variant pointer-sized for its union fields, which is what clippy::large_enum_variant actually cares about. The newly-generated pdaSeed structs box their type and value union fields accordingly; the hand-written constructors wrap with Box::new(...) and the corresponding tests dereference with *node.r#type / *node.value.
