`ci.yml`'s clippy gate has been failing on main since the pre-0.16.0 sweep landed, and because clippy stops at the first crate it can't compile, the visible error was only ever the first of four. `ci.yml` is not tag-triggered, so v0.16.0 cut and shipped over a red main; none of this reaches the release artifacts (the two E0308s are in a test binary and a dev tool, and the rest are lints) but the gate has been blind since. Fixed, in the order clippy surfaced them: - clients/probe failed to COMPILE (E0308, x2). `810d918d` moved `clock_sync` onto the resumable `io::MsgReader` but only updated the client pump, leaving the probe passing a bare `&mut RecvStream`. The probe now wraps the control stream in a `MsgReader` at `open_bi` and threads that everywhere — Welcome, the --remode and --bitrate watchers, and the speed-test result read — which is also what the refactor was for: those reads sit behind timeouts and `select!`, exactly where a straddling frame would desync the stream for the rest of the run. - pf-capture: `SPA_META_Cursor as u32` is a `u32 -> u32` no-op (`clippy::unnecessary_cast`). Line 1274 already passes the same constant uncast, so the type is not in question. - pf-inject: `noop as usize` on the SIGUSR1 wake handler added in `986402f7` trips `clippy::function_casts_as_integer`; goes via `*const ()` as the lint asks. Same value in the `usize`-typed `sa_sigaction` slot. - punktfunk-core: the `ctrl_framing` test module's `use super::*` is unused, which `-D warnings` promotes to an error. Verified with CI's own commands on a Linux box (this is all Linux-gated code, so a Mac cannot check it): `cargo clippy --workspace --all-targets --locked -- -D warnings` finishes clean, `cargo build --workspace --locked` succeeds, and `cargo test --workspace --locked` exits 0 with no failures — including punktfunk-core's 196-test suite, which covers the control-stream framing the probe change touches.
