B-HowellandClaude Opus 4.7 b04c2f2e09 feat(libc): implement lfind and lsearch ...

Add FreeBSD/POSIX lfind and lsearch for the libc PRX, with explicit
guards against null arguments, zero element size, and span arithmetic
that would overflow size_t.  lsearch validates the existing search
range before any comparator call, then separately checks the append
capacity so a matched element never requires room for an extra one.

Extend guest_search to cover first-match on duplicate keys, zero-count
no-op, byte-exact appended payload, zero-count seed, and that the
overflow guard fires without touching element memory or invoking the
callback.  Document the exports in docs/dev/debt/libc.md.
