v0.1.2

Picks up uc386 0.1.1 + uc_core 0.3.5 with the 9 MicroPython-port fixes shipped today. The port build now parses all 211 upstream sources cleanly (was hitting 5 different parse / typedef-shadow errors before). Codegen is making real progress through the multi-TU compile, but there's a separate uc386 perf issue (~50 min runtime) that still needs investigation before freedos-micropython port produces a runnable binary end-to-end.
