Instead of relying on an INPUT_STREAM_CREATED IPC message from the
platform (which was never wired up), the worker now connects the SSE
tail automatically when task code first calls .on() or .once() on an
input stream. The worker receives the run ID via setRunId() at
execution start, and #ensureTailConnected() opens the tail on demand.
This eliminates the need for platform→coordinator→executor→worker IPC
signaling and ensures no race conditions since the SSE tail reads from
the beginning of the __input stream.
