test: move moq-cli's TS verbatim coverage into moq-mux

[kixelated]

Problem

The moq-dev/smoke interop CI's nix channel has been red since ~2026-06-21: nix build .#moq-cli fails to compile because moq-cli's test embedded a sibling crate's fixture across the crate boundary:

const BBB: &[u8] = include_bytes!("../../moq-mux/src/container/ts/test_data/bbb.ts");

crane's cleanCargoSource filters non-Rust files out of the nix build sandbox, so bbb.ts goes missing and the compile-time include_bytes! fails. (The plain cargo channel passes because it has the whole monorepo on disk.)

Change

The moq-cli test (ts_verbatim_streams_round_trip_through_cli) was almost entirely redundant with moq-mux's own coverage, which lives where the fixture lives:

• export_scte35_roundtrip — section-framed SCTE-35, full export round-trip.
• private_pes_carried_verbatim — PES-framed verbatim capture (same stream_id and payload).

The one path only the moq-cli test exercised, a PES-framed verbatim stream surviving a full export round-trip, moves to moq-mux as export_pes_verbatim_roundtrip, using the in-crate test_data/bbb.ts (no cross-crate reach). Net -110 lines.

Public API

None. Both changes are to #[cfg(test)] code; no pub items touched, so this targets main.

Test plan

• cargo test -p moq-mux → 250 passed (incl. the new export_pes_verbatim_roundtrip)
• cargo test -p moq-cli → compiles with --tests, 0 tests, exit 0 (nothing dangling after the removal)
• cargo fmt + clippy clean via the nix devshell (pinned toolchain)
• No include_bytes! left anywhere in moq-cli, so the nix build .#moq-cli compile failure is resolved (CI's nix channel confirms end to end)

Walkthrough

The pull request relocates the MPEG-TS verbatim payload round-trip test from rs/moq-cli/src/publish.rs to rs/moq-mux/src/container/ts/export_test.rs. The entire #[cfg(test)] mod tests block is deleted from the CLI publish module. A new async Tokio test, export_pes_verbatim_roundtrip, is added to the mux export test file; it constructs a synthetic MoQ broadcast with a retained private PES verbatim track (custom PID, stream_id, and fixed payload) alongside real bbb.ts media to drive the clock, exports to TS, re-imports, and asserts that PID, tscat::Framing::Pes, stream_id, and payload bytes are preserved exactly.
