refactor: Split monolithic wasm.vm.opcodes.pas into 119 individual opcode units

- Extract each opcode procedure from wasm.vm.opcodes.pas into its own unit file under src/wasm/vm/opcodes/ following the naming convention wasm.vm.opcode.<name>.pas. The hub file now only imports the individual units and contains initializeOpcodeJumpTable with fully qualified procedure references. - Add missing test coverage for the else opcode (4 tests), bringing the total from 425 to 429 with all tests passing. Files: - 119 new opcode units under src/wasm/vm/opcodes/ - 1 new test: wasm.test.opcode.elseop.pas - Modified: wasm.vm.opcodes.pas (hub-only), wasm.test.pas, build.bat

t3hn3rd	ff65a0d5f0	refactor: build.bat flexible argument parsing, add run & help commands - Replaced positional `%1` checks with a loop-based argument parser so flags (`test`, `clean`, `run`, `help`) work in any order/combination - Added `run` flag: executes `bin\WASURO.exe` after a successful build - Added `help` flag: prints usage info and exits - Fixed `clean` early-exit to also check `DO_RUN` (not just `TESTFLAGS`), so `build.bat clean run` correctly continues to build+run - Added section comment headers (Build, Run) for consistency	2026-02-24 14:57:30 +00:00
