Gate the initial string slice per compatibility level: L1 sources compile everywhere, strlcpy/strlcat only at level >= 2 (PROFILE_GE_2), strcasestr only at level >= 3 (PROFILE_GE_3). Install the generated include/vlibc/features.h under $(vlibc_includedir)/vlibc/ via a dedicated vlibc_featuresdir primary (nodist_nobase is rejected by automake and loses the vlibc/ subpath). Include stddef.h/string.h in vlibc_include_HEADERS. Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus <[email protected]>
