Subject: [PATCH] Fix heap buffer overflow in `jvp_string_append` and
`jvp_string_copy_replace_bad`
In `jvp_string_append`, the allocation size `(currlen + len) * 2` could
overflow `uint32_t` when `currlen + len` exceeds `INT_MAX`, causing a small
allocation followed by a large `memcpy`.
In `jvp_string_copy_replace_bad`, the output buffer size calculation
`length * 3 + 1` could overflow `uint32_t`, again resulting in a small
allocation followed by a large write.
Add overflow checks to both functions to return an error for strings
that would exceed `INT_MAX` in length. Fixes CVE-2026-32316.
(cherry picked from commit e47e56d226519635768e6aab2f38f0ab037c09e5)
