easy_image_gallery_prettyphoto_js previously received/returned a full <script>...</script> block (because $js is built with script tags). The new regex extraction strips the first <script> wrapper and drops any script attributes or additional script tags a filter might add, which is a backward-incompatible change to the filter contract. Consider generating $js as raw JS (no <script> tags) before applying the filter, or only stripping when the output exactly matches the original wrapper format so filtered HTML isn't silently truncated.

Same issue as the prettyPhoto branch: easy_image_gallery_fancybox_js receives a full <script> block, but the new regex stripping + wp_print_inline_script_tag() will drop script attributes and can truncate output if the filter returns more than one <script> tag. Consider switching the buffer to raw JS before filtering, or add stricter handling so filtered output isn't unintentionally altered.

The plugin header version was bumped to 1.5.4, but
EASY_IMAGE_GALLERY_VERSION(used for cache-busting enqueued assets, and now also for block asset versions) is still defined as 1.2. This will prevent users from receiving updated CSS/JS after upgrading unless caches are cleared; align the constant with the plugin version (or derive it from the header).
