Record the 39.6 percent line and 44.3 percent function coverage baseline
measured with the AKGL_COVERAGE build, and plan twelve test suites to raise
it to roughly 70 percent lines and 80 percent functions. Tier the work by
what each suite needs: pure logic suites for physics, json_helpers, heap,
and savegame handling that require no renderer; renderer suites gated behind
a shared offscreen harness; and controller and frame-loop coverage deferred.
Note that vendored dependency shared objects are absent from the loader path
in a fresh out-of-tree build, which reports every test as zero coverage, and
record ten suspected defects found while reading the uncovered code so the
new tests assert correct behavior rather than pinning the current one.
