Implement MBF binary file compatibility, fix binary loader null-byte truncation, update to v0.14.0

evv/gw-basic-2026

Binary tokenized SAVE/LOAD now stores float constants in Microsoft Binary
Format (MBF) on disk, matching original GWBASIC.EXE.  A token-walking function
(convert_floats) converts IEEE↔MBF at the save_binary()/load_binary() boundary.

Also fixes a latent bug where load_binary() scanned for 0x00 to find the end
of each token line — this fails when float bytes contain null (e.g. MBF for
100.5 is 00 00 49 87).  The loader now uses the next-line pointer to compute
token data length, matching the original's approach.
