Puts MEDIA-01 on top of the bus ArtifactRef rather than beside it.
fly-session-types gains the two validators a descriptor and a reference
cannot carry on their own: AudioTimeline, which holds one stream chunk
sequence for one epoch (no overlap, no backwards, the first chunk after a
restore marks the discontinuity), and check_imported_asset, which checks
that a transient artifact carries an installed asset content without ever
converting one identity into the other.
fly-session gains a media module: a ViewPipeline that renders one native
frame per boundary and serves the frame the declared observationDelaySteps
requires (so bootstrap repeats O[0] exactly while the pipeline fills), an
AudioSource with an exact rational sample budget and a deterministic
integer-phase waveform, the Phase C acceptance checks, a latest-subscription
Spectator with finite credits, a SensorLog recording what each agent read,
and an AssetRegistry for installed persistent content.
The counter arena now emits a real 32x24 RGBA8 pattern per boundary and one
audio chunk per transition; the coordinator forwards the one owned view
handle to every agent Commit and publishes the same handle, with the audio
handles, for presentation.
36 new tests: 12 shape rules against the contract crate and 24 session-level
acceptance tests over both transports.
