bridge: mark signedUrlDiskCache and fetchManifest as branch-pending

CI's "MATLAB/Python bridge completeness" checks the bridge against
NDI-matlab main, where +ndi/+cloud/+download/+internal/signedUrlDiskCache.m
and +ndi/+cloud/+sync/+internal/fetchManifest.m do not exist yet: both
live on claude/lightsheet-zarr-ndi-viewer-djp5vk (VH-Lab/NDI-matlab#979).
Add matlab_branch to the two entries, as the bridge reference prescribes
for files on an unmerged branch. Passes against NDI-matlab main and
against the branch.
