The daemon is now an OS service (`heph daemon`); the plugin no longer spawns or
supervises one. Removes the managed-daemon machinery entirely.
- delete lua/heph/daemon.lua (spawn/ensure/stop_spawned/self-heal)
- init.lua: connect-only; probe `health` once and guide to `heph daemon start`
- rpc.lua: drop set_respawn + respawn-on-drop; a dropped connection just
reconnects once (e.g. after `heph daemon restart`), never spawns
- config.lua: drop autostart/bin/db; stable socket fallback (data-dir, matches
hephd::default_socket_path), keep $HEPH_SOCKET for dev isolation
- tests: spawn/wait_ready move into the e2e harness (test infra); rework
managed_daemon_spec into a connect-only spec (connect / clean-fail / reconnect)
16 nvim e2e specs pass.

Recreates a crash-left stale socket (spawn a managed daemon, SIGKILL it) and
asserts wait_ready returns promptly (a deadlock would freeze the suite) and that
a fresh autostart recovers. Verified it fails (suite hangs) against the buggy
nested-vim.wait version.

The plugin now manages its own hephd by default (autostart = true): if nothing
is serving the socket it spawns a local daemon against the default XDG paths,
kills only what it spawned on VimLeavePre, and self-heals — rpc.call retries
once through a respawn hook when the connection drops (the prior owner releases
the DB lock on exit, so a respawn can claim it).
- daemon.ensure() connects to an already-running daemon (any mode) or spawns one
we own; stop_spawned()/is_managed() track lifecycle.
- A server/client daemon you started is always respected (spawn only when nothing
serves the socket). autostart = false → connect-only, warns/errors if down,
and clears the self-heal hook so it fails loudly.
- config: autostart defaults true; new `db` option; $HEPH_SOCKET / $HEPH_DB
fallbacks isolate a dev Neovim onto a separate daemon + DB.
e2e: managed_daemon_spec covers autostart spawn, self-heal-after-kill, and
connect-only error. 10 specs green.
