Fix src/shuriken.sh lib source list missing 5 modules

Running `bash src/shuriken.sh --generate ...` directly from a source
checkout printed "command not found" for camera_label_from_make_model,
photo_exif_values_to and cached_photo_identify_output for every photo,
silently emptying EXIF tooltips/details and, with STATS_PAGE=yes,
omitting the whole stats/ tree. The hand-maintained source list inside
the SHURIKEN_LIB_SOURCES_BEGIN/END marker block had drifted from the
authoritative Justfile LIB_SOURCES, missing metadata-label,
metadata-cache, stats-aggregate, stats-render and stats-filter-album.
`just build` replaces the marker block with LIB_SOURCES when generating
bin/shuriken, so the installed binary and the bin-based test suite never
noticed; only direct src execution was affected.

- Add the 5 missing `source` lines to the marker block in the same order
  as Justfile LIB_SOURCES, so the two lists now match exactly.
- Add tests/cli.sh case test_lib_sources_match_justfile_lib_sources that
  extracts the marker-block module names and asserts they equal the
  Justfile LIB_SOURCES (same set and order) to prevent future drift.
- shellcheck --check-sourced now follows the 5 newly-sourced libs;
  suppress the cross-module nameref false positives (SC2178/SC2128/
  SC2154) with explained directives and genuinely fix SC2004
  (counts_ref[$key] -> [key]) and quote the TITLE default (${TITLE:-}).

bin/shuriken changes only by these propagated lib edits; the marker-block
source list it generates is unchanged.
