0.18 round 2: add FrameSink impls to concrete mux sinks

Browse Source 
Per-impl migration of MkvStream / M2tsStream / NetworkStream /
NullStream / StdioStream from the deprecated pes::Stream trait
to the typed pes::FrameSink trait. Both impls coexist during
the 0.18 deprecation window — the existing Stream impls are
unchanged.

The FrameSink::finish signature differs (Box<Self> vs &mut self),
which is why this couldn't be a blanket impl. Each migration
re-borrows the box and delegates to the underlying Stream::finish
body.

FrameSink: Send forced two struct fields (M2tsStream's boxed
Write/Read, MkvStream's boxed WriteSeek/Read) to gain `+ Send`
bounds — minimum surface needed to make the Send-bounded trait
impl-able. mux::resolve::output's local Box<dyn WriteSeek>
construction picks up the same `+ Send`. tests/streams.rs's
shared `stream.write/.finish/.info/.read` calls were
disambiguated to `PesStream::*` to resolve the now-multiple
candidates from coexisting trait impls.

Caller migration (mux::resolve::output return type, autorip,
CLI) is a later slice. This commit only adds new impls; nothing
removed.

See (internal)/memory/0_18_redesign.md.
