Add var _ Interface = (*ConcreteType)(nil) assertions for:
- *flamegraph.LiveTrie → runtime.{Snapshotter,Configurator,LiveTrieSource}
and tui/flamegraph.{Snapshotter,Configurator,LiveTrieSource}
- *probemanager.Manager → runtime.ProbeManager
- *statsengine.Engine → runtime.SnapshotSource
- *streamrow.RingBuffer → runtime.EventSink
- *runtimeBindings (tui) → runtime.TraceRuntimeBindings
- *lateBoundDashboardSource → dashboard.SnapshotSource
- libbpfTracepointProgram/Module → probemanager.{Program,Attacher}
Assertions are grouped close to their interface definitions to avoid
introducing new import cycles (runtime already imports all affected
packages; tui/flamegraph already imports coreflamegraph).

Applies the Interface Segregation Principle to LiveTrieSource in both
internal/runtime and internal/tui/flamegraph. The monolithic interface is
replaced by two focused sub-interfaces — Snapshotter (read-only: Version,
SnapshotJSON, SnapshotTree) and Configurator (mutating: Fields, CountField,
Reconfigure, SetCountField, Reset) — which LiveTrieSource then embeds so all
existing consumers continue to compile unchanged. The buildSnapshotMsg helper
is narrowed to Snapshotter since it only reads snapshot data, preventing
accidental mutation from the background goroutine.

Introduce internal/runtime as a neutral contract package that both the
core engine (internal) and the TUI layer (internal/tui) depend on.
- internal/runtime: defines TraceStarter, StreamSource, EventSink,
LiveTrieSource, SnapshotSource, ProbeManager, RuntimePublisher,
RuntimeState, TraceRuntimeBindings, and all context key/helper
functions (RuntimeBindingsFromContext, RuntimePublisherFromContext,
ContextWithRuntimeBindings, ContextWithTraceFilters,
TraceFiltersFromContext). These were previously defined in
internal/tui, forcing the core package to import the TUI layer.
- internal/streamrow: add RingBuffer (moved from internal/tui/eventstream)
so the core tracing engine can use the ring buffer without importing
the TUI layer.
- internal/tui/eventstream/ringbuffer.go: change to a thin re-export of
streamrow.RingBuffer via a type alias, preserving the existing API for
all callers within the TUI layer.
- internal/tui/tui.go: replace locally-defined interface declarations
(TraceStarter, SnapshotSource, ProbeManager, RuntimePublisher,
RuntimeState, TraceRuntimeBindings) with type aliases from
internal/runtime. Delegate all context helper functions to runtime.
- internal/ior.go, internal/ior_bpfsetup.go: remove imports of
internal/tui and internal/tui/eventstream; use internal/runtime and
internal/streamrow instead. Add SetTUIRunners injection point so the
concrete TUI runner functions are wired in by cmd/ior/main.go.
- cmd/ior/main.go: call internal.SetTUIRunners with the concrete TUI
runner functions before internal.Run, completing the wiring without
creating a cycle.
- Test files (internal/ior_mode_test.go, internal/bench_pipeline_test.go):
updated to use runtime.* and streamrow.* types in place of tui.* and
eventstream.* types.
