Add an .engine RuntimeEvent source so host-tier issues
(devices, packages, attach, spawn-gating, instruments,
hookpacks, repl, itrace, editor) flow into the existing
event stream instead of stdout. HookPackLibrary takes a
callback for decode errors, and ITraceDecoder returns
collected panic strings so ProcessNode can yield them as
engine events.
Move pure data types out of Luma/ into Sources/LumaCore/
so they can be shared with the GTK frontend:
- AddressAnchor, CFGGraph, ITraceDecoder (+ all related
types: TraceEntry, ITraceMetadata, RegisterState, etc.)
- JSInspectValue, SpawnConfig, ProcessModule
- HookPackConfig, HookPackManifest, InstrumentConfigCodec
- InstrumentIcon, InstrumentKind, ConsoleLevel
CFGGraph uses its own Point2D instead of CoreGraphics
types, keeping the core free of Apple frameworks.
Remove premature stubs (Engine, ProcessNode,
InstrumentRuntime, EventStream) that will be properly
built in a later phase once the real implementations
are ready to move.
