fix: silence bootstrap lifecycle events (plugin.added, connector.updated, reference.updated)

[pruiz]

Problem

New opencode versions emit plugin.added, connector.updated, and reference.updated SSE events during server bootstrap. These hit the UnknownEventRenderer fallback, producing dozens of unknown event type lines per run.

Solution

Drop them silently in StateTracker.ingest() alongside the existing session.updated filter. Events are still recorded in the JSONL transcript for debugging.

Changes

• tools/events/state_tracker.py — Added the three event types to the silent-drop block.
• tests/test_new_serve_stack.py — Parametrized test verifying all three return [] from ingest().

Testing

make tests — 844 passed.

Greptile Summary

Silences three bootstrap-phase SSE events (plugin.added, connector.updated, reference.updated) by adding them to the existing silent-drop branch in StateTracker.ingest(), eliminating the spurious unknown event type noise produced by new opencode versions on startup.

• tools/events/state_tracker.py: The three new event types join session.updated in a single in-tuple check that returns [], following the exact same pattern already in place.
• tests/test_new_serve_stack.py: A parametrized test covers all three types, confirming each produces an empty list from ingest().

Confidence Score: 5/5

Safe to merge — the change is a narrow, well-tested addition to an existing silent-drop guard with no effect on other event paths.

The diff touches only two places: a single conditional in ingest() and a matching parametrized test. The three new event types are dropped the same way session.updated has always been dropped, and the test suite (844 passing) validates this directly. No existing behaviour is altered.

No files require special attention.

Important Files Changed

Filename	Overview
tools/events/state_tracker.py	Added three bootstrap lifecycle event types to the existing silent-drop branch; logic is minimal and follows the established pattern exactly.
tests/test_new_serve_stack.py	Parametrized test covering all three new silent-drop event types; each assertion checks that ingest() returns [], which correctly captures the intended behaviour.
