# One-time environment setup for a fresh git worktree.
#
# A new worktree is just a source checkout — it has no venv, the pipecat
# submodule isn't checked out, and ui/node_modules may be missing. This wires
# up an ISOLATED environment so the worktree can run independently (its own
# editable pipecat install points at THIS worktree's pipecat, so pipecat edits
# here take effect).
#
# Heavy (minutes) — deliberately NOT a folderOpen task. Run it once per worktree:
#   ./scripts/setup-worktree.sh        (or VS Code: Run Task -> "Setup worktree environment")
#
# Fast on repeat: uv hardlinks wheels from its global cache, npm uses its cache.
