Generate contextualValue nodes; align Rust variant names with the derived rule

[lorisleiva]

This PR brings the contextualValue category into the generator (10 nodes, 6 emittable inline unions, and the RegisteredContextualValueNode category union via the RegisteredNodes derive). All inline unions flow through the PR #6 derived rule with no per-union config. To keep the generator override-free, the Rust crate is updated to match the derived variant names: PdaValuePda::{Linked, Nested} becomes {PdaLink, Pda} (pdaLinkNode and pdaNode share only the Node suffix, so that's all the rule can strip), and the 23 *ValueNode variants of InstructionInputValueNode gain a Value suffix while ProgramLink stays unchanged (members share only Node as a common suffix, since programLinkNode mixes with value nodes). The From<ValueNode> / TryFrom<\u2026 > for ValueNode bridges in shared/instruction_input_value_node.rs are preserved and updated for the new variant names; the enum itself moves to generated/contextual_value_nodes/. resolverValueNode.dependsOn changes from Option<Vec<ResolverDependency>> to bare Vec<ResolverDependency> to match the optional-array convention every other node uses. Hand-written contextual_value_nodes/*.rs files shrink to constructors and #[cfg(test)] mod tests. The RegisteredNodes renderer is fixed to compute its variant-name strip suffix from the actual leaf members (ValueNode) rather than the union's own pascal-case name (ContextualValueNode); this was a latent bug that worked by coincidence for value but would have produced wrong variant names for contextualValue.
