fix: Windows command quoting, atomic JSON/log writes, restore dropped test

Implements items 1-3 of the whole-project review's suggested order
(docs/PROJECT_REVIEW_PLAN.md):

- Restore TestJobListViewIsCompact, accidentally dropped by 5b0e6fe;
  drop the redundant TestDefaultConfigUsesDetailedJobList row from
  TESTS.md and document the two other doc gaps the review found.
- Fix quoteLeadingWindowsProgramPath to find the earliest file-extension
  match at a word boundary instead of the first extension in list order,
  so a .bat/.cmd command whose argument ends in .exe no longer has its
  whole command line mistaken for the program path.
- Write gosentry.json, jobs.json, and run log files atomically (temp
  file + rename) so a crash or power loss mid-write can no longer leave
  a truncated file. Wire Service.Stop() into the app shutdown path so
  it actually runs, cancelling the run context for in-flight runs.
