Subject: [PATCH] feat(monorel): pre-compute release notes into the generated
 script

Instead of emitting a runtime git log command in Step 4, run git log at
monorel-invocation time and embed the actual commit list as a
single-quoted bash string (with '\'' escaping for embedded apostrophes).

  my_release_notes='- abc1234 first commit
  - def5678 fix: don'\''t crash'

This makes the generated script self-contained and shows the user exactly
which commits will appear in the release notes before they run the script.
Removes the now-unused gitPathSpec local variable.
