v0.7.0 — bring your own exercises

The built-in twelve are a starting point, not a prescription. Now you can replace them:

mkdir -p ~/.config/vibestretch
cat > ~/.config/vibestretch/exercises.txt <<'LIST'
# blank lines and comments are skipped
Refill the water glass. Yes, now.
Hang from the pull-up bar for 20 seconds.
Look out the window and find something green.
LIST

Point VIBESTRETCH_EXERCISES somewhere else if you'd rather keep the file elsewhere — per-project lists work that way too. Rotation walks your list in order, quotes and backslashes in your text are safe, and a file that exists but has nothing usable in it falls back to the built-ins rather than nudging you with a blank line.

This closes the roadmap the plugin shipped with: Codex, Gemini, and your own exercises.
