chore(todo): reconcile test-coverage tracking with current state

After this session's coverage push (68.8% -> 86.5%), 28 of the 30
child modules listed in the coverage-below-70% task have crossed the
threshold.  Mark them DONE with their new percentages, leave the two
genuinely-blocked modules (system-defaults.el at 8.3% and
system-commands.el at 69.4%) as TODO with notes explaining the
instrumentation-gap reason each is stuck.

Also: drop the stray =p= from the parent heading.
