- One name, as review asked: TrackProcessorContext becomes
BackgroundEffectsContext, with BackgroundEffectsProvider,
BackgroundEffectsState, useBackgroundEffects,
useBackgroundEffectsState$ and useSyncBackgroundEffects.
- The state's Behavior is backgroundEffectsState$ wherever it is passed,
in place of trackProcessorState$, trackerProcessorState$ and
processorState$.
- Renames only: nothing changes in behaviour.

- The Vite transform wrapper takes Vite's own types, with no cast.
- The pipeline's options are compared with deepCompare, not as JSON.
- Renames `attached` to `enable` and shortens the pipeline's doc comment.
- Drops a comment that blamed an ended track on the pipeline's queue.

- One pipeline, shared by the pre-join preview and the call, attached the
first time an effect is wanted and never detached after; turning blur
off switches it to a disabled mode in place. Main dropped the processor
whenever blur went off, and a pipeline taken off the camera is destroyed
and re-primed, so each time blur came back one unprocessed frame went
out. Built once, the priming frame is spent once.
- Still driven by the existing blur setting: nothing a user sees changes.
- Its logic is BackgroundEffects in src/state/, which the provider only
builds, so the tests drive it without rendering anything.
- Disabled drops the blur radius too. The SDK's disabled mode keeps it,
and with a radius every frame is still segmented and thrown away; with
neither a radius nor a picture, frames pass untouched.
- Switches run one at a time and skip any overtaken, so an earlier,
slower switch can't land after a later choice.
- Builds, rebuilds and teardowns of the pipeline run one at a time
(OneStepPipeline). The preview's and the call's tracks attach and stop
it independently, and the SDK's wrapper holds one track's streams: two
builds at once overwrite each other's, and a stop during a build does
nothing.
- Every camera track starts with the pipeline on: the room's capture
defaults follow it, and a camera turned off before the first effect is
replaced on turning it on, since a stopped track can't take one. One
attached after publishing lets the room through while it is built.
- BlurBackgroundTransformer becomes BackgroundEffectTransformer: it also
sits disabled, and its init applies that state as the SDK's would.
