Rosetta Code Compiler Stress Test

Methodically implement Rosetta Code tasks in Ori, treating each program as a deep language evaluation: push Ori's full feature set (generics, pattern matching, closures, traits, iterators, sum types, as/as?, everything) to write the most elegant version possible, then run the complete diagnostic/verification/benchmark battery to surface compiler bugs, codegen issues, memory leaks, performance problems, and language design gaps. The bugs found, language insights recorded, and compiler improvements made are the primary deliverable — the Rosetta tasks are fuel.
