enricobuehlerandClaude Opus 5 ff01db67ff fix(client): punktfunk-session is the session binary again — 0.22.0 shipped the shell's stub
Connecting from the 0.22.0 Windows client bounces straight back to the host list, on
every host. The shell is fine; the binary it spawns is not.

b0ea1e6b was a `clients/linux` change that also dropped a verbatim copy of the GTK
shell into `clients/session/src/` — app.rs, cli.rs, the four ui_*.rs, shortcuts.rs,
spawn.rs — and, fatally, OVERWROTE `clients/session/src/main.rs` with the shell's.
That file is `[[bin]] punktfunk-session`. So the binary every shell execs for a stream
stopped being the Vulkan session and became the GTK shell:

  - Windows: the shell's `#[cfg(not(target_os = "linux"))]` arm — print
    "punktfunk-client is Linux-only" to stderr, `exit(2)`. It never writes a single
    line of the stdout contract, so the shell sees EOF with no `ready`, no `error`,
    no `ended`, and returns to the host list with a BLANK banner. Exactly the report.
  - Linux: `app::run()` sees `--connect` in argv and calls `exec_session()`, which
    execs `punktfunk-session` — itself. A stream is an exec loop.

CI could not catch it. The Windows leg of the clobbered file is a three-line stub that
compiles perfectly; `cargo build -p punktfunk-client-session` stayed green while
building the wrong program. Only running it fails, and nothing runs it.

61bdf11e then read the 327 E0433s on the Linux leg as a missing-manifest bug and
declared gtk4/libadwaita/relm4 on this crate. That fixed the build of the wrong file
and cemented the clobber. Both go: the copy is deleted, `main.rs` is restored from
bf981027 (the last commit that touched the real one), and the manifest loses the GTK
block plus the gresource build-dep and `data/` that arrived with 944c03dd to feed it.
serde_json returns to `optional`/`ui`, which is what it always was — the reason
`--no-default-features` didn't compile was cli.rs, and cli.rs was never ours.

Also closes the hole that made this silent. `SpawnEvent::Exited` now carries the
child's exit code, and a child that exits nonzero having said NOTHING gets a banner
naming that code instead of an empty string. Code 0 (stream window closed) and -1
(our own Disconnect/Cancel kill) stay silent, as before. A wrong or crashing session
binary is now a legible failure rather than a connect that quietly does nothing.

Verified. Windows x86_64 on the CI runner: check, clippy -D warnings, rustfmt, tests
(5 passed, incl. the new one) all green, and the rebuilt punktfunk-session.exe answers
`--connect` with `{"error":"presenter: SDL window: …"}` — the real contract — where
0.22.0's answered with nothing. Linux amd64 in the CI image: check with default AND
--no-default-features, clippy -D warnings, rustfmt, tests green, and the built binary
emits `{"error":"presenter: SDL video: …"}` + exit 4 instead of exec-looping.
