- oakrender: renderer/texture/frame/cache/colorprocessor/ticket/copier
all become by-value {ctx, addref, release, abi_version} handles over a
generic box; retain() folds into addref; new
oakrender_cache_wrap_borrowed for native caches from oaknode
- oaktimeline: marker list/workarea borrowed handles become value
handles (non-owning boxes) with explicit free
- oaktask: OakTaskTask becomes a value handle; ownership still moves
to the manager on start (owns flag flips)
- consumers (timeline/task/codec sources) migrated; tests everywhere
updated; suites green: render 45, timeline 117, task 106, node 96,
common 193, codec 18, audio 36
