chore: delete dead pyautoheart/ compat shim (Pulse retirement leftover)

The pyautoheart/ package was a 6-line 'from heart import *' shim created
by the PyAutoPulse->PyAutoHeart rename (#18) and missed by the Phase-2
compat-surface retirement (#28). Zero importers workspace-wide; the
distribution name in pyproject.toml is unchanged.

Closes #80.
