Poem

🐰 I hopped and found a tempdir bright,

No more constants in the night,
I build the path, then free with care,
Tests prance lightly, tidy and fair.

In `@tests/internal/input_chunk_routes.c`:
- Around line 338-356: The env_tmpdir function currently checks TMPDIR then TMP
and falls back to "/tmp", which fails on Windows when TEMP is set but TMP is
not; update env_tmpdir to also check getenv("TEMP") before the fallback and on
Windows use a Windows-appropriate fallback (either call
GetTempPathA()/GetTempPathW when available or use "C:\\Temp") instead of "/tmp",
returning the result via flb_strdup to match existing allocation behavior.

20-21: Remove duplicate flb_mem.h include.

<fluent-bit/flb_mem.h> is already included at Line 10, so the Line 20 include is redundant.

♻️ Suggested cleanup

-#include <fluent-bit/flb_mem.h>
 `#include` <fluent-bit/flb_str.h>
