ide-plugin: live LuaBridge tool window (connect, NPC inspector, world queries, console)

[devin-ai-integration]

Summary

Replaces the static tool-window stub with a live LuaBridge panel.

Split that matters: LuaBridgeSession is IntelliJ-free — all socket I/O runs on a single daemon executor; state changes reach the Swing layer through an injected dispatcher (SwingUtilities::invokeLater in production, Runnable::run in tests). LuaMapToolWindowPanel is pure EDT-side rendering.

• Session: connect/disconnect/reconnect, states DISCONNECTED/CONNECTING/CONNECTED/ERROR, status poll every 2 s while connected, one auto-reconnect attempt per 1.5 s (toggleable), refresh/queryBlock/listScripts/runScript/eval convenience requests. NPCs come from eval of NPC_LIST_LUA (npc.list() → sorted name,x,y,z CSV — LuaJ has no JSON serializer) — no protocol change needed.
• Panel: host/port fields, Connect/Disconnect/Reconnect, status badge + detail text, Auto-reconnect and Auto-refresh checkboxes (poll listener re-pulls the NPC table), NPC inspector table, world.getblock query row, script list + Run, eval console.
• Lifecycle: factory registers the panel as Disposable under the content — closing the window/project stops polling, closes the socket, and shuts the executor down.
• Tests: MockBridgeServer (loopback NDJSON) + 11 tests covering connect/error/disconnect transitions, drop→auto-reconnect, NPC/status parsing, block+eval replies, script list, protocol framing, and non-blocking connect().
• Build plumbing: the platform test task is disabled — on the unified 2025.3 distro it crashes (missing coroutines-debug javaagent, then java.base/sun.nio.fs module export under PathClassLoader) — replaced by plain-JVM unitTest on the 21 toolchain, wired into check on both sides (launcher check also depends on it). Verified plugin.xml range unchanged: since-build="241", no until-build.

Verified: ./gradlew clean build — BUILD SUCCESSFUL, 0 failures (bridge 11 + mod 37 + launcher 25 + ide-plugin 11 = 84). Tool-window visual/EDT behavior not exercised on headless VM — the IntelliJ-free split is what makes the logic unit-testable at all.
