fix(host): do not attach acquire to a stopped autopg port

[simoncrypta]

Summary

• cedarpg acquire --force no longer treats a registered-but-stopped autopg (pm2 status: stopped, port 25432) as live, which produced ECONNREFUSED 127.0.0.1:25432.
• Attach requires TCP on the discovered port. Ephemeral start is detached autopg postmaster only (no install --no-pm2, so ~/.autopg/admin.json is left alone).
• Default local acquire: try autopg install, then an owned postmaster on 55432 if install fails or still has no listener. CEDAR_PG_EPHEMERAL_HOST=0 keeps the fail-closed pm2 path.

Test plan

• vp check and vp test (86)
• cedarpg acquire --force with autopg stopped, no CI / CEDAR_PG_EPHEMERAL_HOST → URL on 55432, not 25432
• CEDAR_PG_EPHEMERAL_HOST=0 still fails and does not start 55432
• vp run smoke:pg (Vitest, Jest, CLI acquire/run/dispose)
• ~/.autopg/admin.json unchanged next to local pm2
