v0.22.6

Fixed

• TypeError when CHUNKY_CHUNK_SIZE is set in .env. env() always returns strings, and ChunkCalculator::chunkSize() — declared int under strict_types=1 — returned the config value uncast, so any app that set CHUNKY_CHUNK_SIZE crashed on the first initiate request with Return value must be of type int, string returned. The calculator now casts the config read to int, which also fixes apps running an already-published config/chunky.php without re-publishing. The shipped config additionally casts (int) env('CHUNKY_CHUNK_SIZE', ...) at the source. A regression test covers the string-valued config path.
