docs(todo): refresh coverage status after 5-module push

Coverage rerun after this session's test additions: 67.2% -> 68.8% (4716/6853 lines across 73 files).

Four modules crossed the 70% threshold and are marked DONE: browser-config 69.7% -> 81.6%, ui-config 64.5% -> 90.3%, custom-whitespace 64.6% -> 97.6%, jumper 64.6% -> 98.0%.

system-defaults stays open with a note: 8 new tests cover its helpers (`cj/disabled`, the gc-threshold hooks, `unpropertize-kill-ring`, `cj/log-comp-warning`) but the gauge still reads 1/12 because the sandboxed `(load ...)` used to skip startup side effects doesn't register with undercover's instrumentation. Closing it needs either a refactor that lets the module load via plain `(require)` in batch, or a different coverage strategy.

Other numbers refreshed where they shifted (ui-navigation 8.7% -> 54.2% from prior session, org-agenda-config 60.0% -> 67.3% from this session's project-name category work, etc.).
