p5-Crypt-PBKDF2: update to 0.261630.
Version 0.261630: 2026-06-11
* Change the default hash algorithm to HMAC-SHA256, and increase the
default number of iterations to 600,000, in line with current OWASP
recommendations (CVE-2026-9641).
* Generate salts using Crypt::URandom (a strong system RNG) instead of
perl's builtin `rand()`, which is not cryptographically secure
(CVE-2026-9638).
* Use a constant-time comparison in `validate` to avoid timing attacks
(CVE-2017-20240).
