Impl blocks are anonymous (no declName), so a parameterised-protocol impl in a module reached via a diamond import was appended once per path and registered twice — 'duplicate impl Into for source s64'. mergeFlat and the directory-import merge loop now also dedup by node pointer; a physical AST node is lowered once regardless of how many import paths reach it. Regression: examples/issue-0056-diamond-param-impl.sx.

// A parameterised-protocol (`Into`) impl living in a module reachable through

// more than one import path. Each path must NOT re-register the impl.

// Impl blocks are anonymous (`declName() == null`), so the diamond-import

// dedup in imports.zig (`mergeFlat`) skips them and appends the node once per

// path — `registerParamImpl` then trips its same-file duplicate check.
