Use the tunnel subprocess' stdin for sending control messages and
stdout for receiving control events, instead of a separate Unix
domain socket. This eliminates:
- Temporary directory creation (/tmp/sc-<random>/)
- Socket path and auth token in config JSON
- Connection retry loop (50x at 200ms)
- Auth message handshake
- Socket cleanup on call end
The tunnel's stderr is captured separately for logging. Config JSON
is written as the first line on stdin, followed by control messages.

Call events are no longer subscribed by default. JSON-RPC clients must
explicitly call subscribeCallEvents to receive callEvent notifications
and enable incoming call handling. This avoids sending unwanted call
events to clients that don't use voice calling.
Also adds unsubscribeCallEvents for cleanup, idempotent subscription
guard, and updates CALL_TUNNEL.md to document the subscription step.

Replace all manual JSON string concatenation with Jackson ObjectNode
construction and ObjectMapper serialization. Use BigInteger for call
IDs to properly represent unsigned 64-bit values in JSON.

Skip processing incoming call offers when no call event listeners are
registered, since there is nobody to notify about the call. For hangup
and busy, also guard when there are no listeners AND no active call
(the tunnel may still need cleanup if already spawned).

Replace explicit null check and Number cast with instanceof pattern
matching in AcceptCallCommand, HangupCallCommand, and
RejectCallCommand.

Successful commands with no additional information should not return
a response, matching the pattern used by other signal-cli commands
like SendSyncRequestCommand and UpdateConfigurationCommand.

The signal.cli.install.dir system property was never set by the Gradle
start script or anywhere else. Replace it with code source detection:
resolve the jar's parent directory to find the install root, then look
for bin/signal-call-tunnel relative to that.

The excludeTags("integration") block was added but no tests use the
@Tag("integration") annotation. Revert to upstream's simple
useJUnitPlatform() call.

Add documentation about the architecture, protocol, and implementation of
signal-call-tunnel, the secure tunnel subprocess for voice calling.

Add startCall, acceptCall, hangupCall, rejectCall, and listCalls
commands for the JSON-RPC daemon interface. Register commands and
update GraalVM metadata for native image support.

Add CallSignalingHelper for x25519 key generation and HKDF-based SRTP
key derivation. Add CallManager for tracking active calls, spawning
call tunnel subprocesses, and handling call lifecycle (offer, answer,
ICE candidates, hangup, busy). Wire call message routing in
IncomingMessageHandler and implement Manager call methods in ManagerImpl.

Define call method interfaces in Manager, create API records (CallInfo,
CallOffer, TurnServer), and hand-coded protobuf parsers for RingRTC
signaling messages (ConnectionParametersV4, RtpDataMessage).

* Add --no-push flag to send command
Expose the server's `urgent` parameter so callers can skip sending a
push notification (FCM/APNs) to the recipient. The message is still
delivered in real-time over WebSocket if the recipient's app is active.
The flag is added to the Message record (following the same pattern as
viewOnce) and threaded through ManagerImpl and SendHelper, keeping the
Manager interface unchanged.
* Rename --no-push flag to --no-urgent
Align with the protocol naming as suggested by the maintainer.
The flag controls the 'urgent' parameter on the server request.
