lmcp: bump to 1.2.4 (shell timeout-kill fix + kill_job/list_jobs)

Ships marfrit/lmcp v1.2.4: shell/shell_bg kills the whole process group on
timeout/cancel (no orphans) + new kill_job/list_jobs tools. Updates arch
PKGBUILD (pkgver + sha256) and debian changelog.

 ## Known caveats
 
-- **`CONFIG_SHADOW_CALL_STACK=n`** in the config: GCC 15.2.1 fails to
-  build `arch/arm64/lib/xor-neon.c` with `arm_neon.h` `#pragma GCC
-  target()` blocks and `-fsanitize=shadow-call-stack`. See
-  `reference_arm64_scs_arm_neon_gcc15` memory and the Makefile
-  workaround patch included in the cumulative. Track upstream GCC
-  resolution before re-enabling.
 - The `cumulative-c5x-danctnix` series-dir in kernel-agent is currently
   a single-file interim (the working hand-curated cumulative) because
   the per-series mirrors created in `kernel-agent#17` use DKMS-style
