feat: make module paths and entry points configurable

* Added functions to set mod dir, temp dir name, and module init/shutdown function names.
* Replaced hardcoded string literals with configurable static buffers in module.c.
* Improved string safety by replacing sprintf with strncpy/strncat.
* Updated stk_init local path buffers to handle maximum combined path lengths.
