ywhkkx e5636eb23c fs/pseudofile: fix buffer sizing and sparse growth. 
Grow the in-memory pseudofile buffer by doubling instead of
1<<LOG2_CEIL, which can under-allocate on 32-bit targets for large
expand sizes. Also:
* reject size_t wrap before expand on write (-EFBIG)
* clear newly addressed bytes when the file grows
* route truncate growth through the same expand path

Impact: CONFIG_PSEUDOFS_FILE expand/write/truncate only; no API or
build-system change.

Testing: host arithmetic PoC blocked; WSL sim:pseudofile-poc
(SIM_M32+KASAN) write returns -ENOMEM instead of SIGSEGV in memcpy.
