Changelog

Unreleased

Updated the deps/libgphoto2 submodule to track the official gphoto/libgphoto2 repository and the latest master commit (a209fc7061903246ce3e6a74b05a3289dbb2b7b1).
Added patches/libgphoto2-emscripten.patch and wired it into the build so our Emscripten-specific tweaks are applied automatically before configuring libgphoto2.
Taught the Makefile to detect the generated ptp2.la and usb1.la paths dynamically, avoiding hard-coded version directories when linking the wasm module.
Included the patch package in the Docker toolchain image to support patch application during npm run build:wasm.
Regenerated build/libapi.wasm against libgphoto2 2.5.32.1 / libgphoto2_port 0.12.2 using the refreshed toolchain.
