feat: bux test runner, bitwise-not parsing, stdlib discovery hardening\n\n- Add 'bux test' runner: discovers tests/*.bux, builds each in a temp package, runs and reports PASS/FAIL.\n- Fix unary ~ parsing and C emission in self-hosted compiler.\n- Harden stdlib discovery (require Fs.bux, avoid system /lib) and lstat in directory traversal.\n- Selfhost loop passes: buxc2 builds src/ and produces identical C output + stripped binary.\n- Update PLAN.md with completed milestones.
