The e2e case from #1444 spawns the real CLI, whose module load imports
../dist/index.html and ../dist/review.html. Dev machines always have
those built, but CI's test job does not build the apps, so the spawn
died at import time with 'Cannot find module' before the guard ran and
the assertion on the unknown-command message failed, breaking main.
The test now drops empty placeholders for any missing artifact before
spawning and removes exactly what it created afterwards; a real dist is
never touched (verified with sentinel content). The guard under test
exits before either page is served, so placeholder content is
irrelevant.
A typo'd subcommand fell through the dispatcher to the plan-hook path,
which reads the hook payload from stdin. From a terminal that stdin never
closes, so `plannotator annotatte README.md` hung with no output instead
of reporting the typo.
Reject an unrecognized first token before the dispatcher runs: print the
offending word, the nearest documented command, and a pointer to --help,
then exit 1. Flags and the no-argument hook invocation are left alone so
the real hook path is untouched.
