Implements the Tier-1 pane subsystem from D-006: spawn / list / focus /
close / write / resize / tail commands, plus pane.spawned / output /
exit / resized / focused / closed events. PaneRegistry owns per-pane
PtySession lifecycles and id generation (p_N); a DaemonEventSink seam
keeps pane code decoupled from the IPC server package.
DaemonServer.broadcast() fans events out to every connected client.
Per-client subsystem/id filtering (`tail --filter pane:p_7`) is
deferred — Tier 1 broadcasts everything and the subscriber discards.
Panes carry a `kind:` field (terminal | claude). Step 7 (builtin.claude)
adds the claude-specific pane flow on top of this generic substrate —
the subsystem itself stays neutral.
14 new core tests: registry unit coverage (spawn → pane.spawned event,
output → base64 events, write/resize/close round-trips, idempotent
close, claude kind on the wire) plus dispatcher coverage (argv
validation, unknown-id → not-found, text vs bytes_b64, etc). All 37
core tests pass in ~3s under test-core.

First real content for the `clide` Dart package at the repo root.
One AOT-compiled binary (ADR 0005) with two modes:
* `clide --daemon` long-running unix-socket server; listens on
`$XDG_RUNTIME_DIR/clide-$USER.sock` with stale-socket
reclaim, accepts JSON-lines request/response traffic, clean
SIGTERM shutdown unlinks the socket file.
* `clide <subcommand>` one-shot; opens the socket, sends a
request, writes the response JSON to stdout, exits with the
dispatcher's error code per ADR 0006 (0/1/2/3/4). Unknown
subcommands forward to the daemon so extensions can register
their own without CLI changes.
Tier 0 handlers: `ping` (returns pong + version + UTC ts) and
`version`. Both are covered by `test/ipc/` + `test/daemon/`; the
subprocess test builds `bin/clide`, starts it, pings it, SIGTERMs
it, and asserts the socket file disappears.
