80-dotfiles.sh was reading notes/aliases.zsh and notes/gitconfig.txt,
but notes/ is gitignored - fresh clones on the dev VM hit "file not
found" and the script aborted.
Move both templates to docs/setup/dotfiles/ where they ship with every
clone. gitconfig.txt's [user] block now carries placeholder identity
(your name / your.email@example.com) instead of the original author's
identity - the script overlays the prompted values at install time so
the file content doesn't matter functionally, but the placeholders
read more clearly as "fill me in".
80-dotfiles.sh source paths flipped from $REPO_ROOT/notes/... to
$REPO_ROOT/docs/setup/dotfiles/.... Step-3 table row, §8.4 (dotfiles
repo appendix), and the setup README index updated accordingly. New
"dotfiles/" section in the setup README documents the folder.
The notes/aliases.zsh and notes/gitconfig.txt on existing dev
workstations are unaffected - those files live outside the repo and
this PR doesn't touch them.
