fix(v1.0.2): Array grow from 0, Map/Set rehash, checked div/mod

- Array_Push grows from cap 0 (same min as Insert) to avoid segfault
- Map/StringMap/Set: default min cap 8 and auto-rehash at ~50% load
- Integer / and % emit bux_div_i64 / bux_mod_i64 (panic instead of SIGFPE)
- Bump version to 1.0.2; stdlib golden regressions; fmt clean
