os.tmpname() Override

LDE overrides os.tmpname() with a safe cross-platform replacement in both the runtime and compiled binaries.

This is needed for Termux/Android, where the default os.tmpname() returns paths that don’t exist.

The replacement generates paths under the system temp directory (TMPDIR / TEMP / TMP) in the form:

<tmpdir>/lde_<timestamp>_<counter>.tmp

The override is active in:

• lde run / lde test — applied for the duration of script execution, then restored.
• lde compile — patched into the compiled binary so it is always in effect.
