Split the framework-free half of tty7 into `tty7-core` and add a headless
`tty7-server` built on it, so a workspace's filesystem, git and session state
can live on another machine while the GUI stays where it is.
- `crates/tty7-core`: wire protocol, session daemon, PTY, native SSH engine and
the domain model, with no gpui dependency. Module paths are unchanged.
- `crates/tty7-server`: the same daemon with no GUI attached, linked fully
static against musl and pushed onto the remote box. One dependency, on
purpose — a second one the GUI also needs belongs in core.
- `Host` trait + `HostId`/`HostRegistry`: every fs/git/watch call a workspace
makes goes through the machine it belongs to. `LocalHost` answers on this
box, `RemoteHost` over a routed control connection.
- `ui::host_ops`: the GUI's single door to a `Host`. Host calls block, so all
of them run on the background executor with the result landed on the UI
thread; de-duplication, staleness and error reporting live here rather than
at each call site. Enforced by a CI grep.
- Connect flow: home page → pick a configured SSH host → the machine's own
workspace list → a window bound to one workspace on it. Workspace switcher
groups by machine, this computer included.
- CI: static musl builds of `tty7-server` for x86_64/aarch64 via
cargo-zigbuild, a host-boundary grep, and version stamping factored out of
the nightly workflow. Both new jobs are non-required so branch protection
does not wedge open PRs.
Design and the interface contract it was built to are in
`docs/2026-07-27-remote-workspace-{design,impl-contract}.md`.
The [Code] block comment used Pascal { } braces, but {tmp} inside it
closed the comment early, so ISCC parsed the trailing prose as code and
aborted with "'BEGIN' expected" — no Windows installer was produced.
Switch the comment to (* *) so brace-form constants stay literal.
The persistent daemon (`tty7.exe --daemon`) is a detached background process
that outlives the GUI and is the running image of tty7.exe, so Windows locks
the file. An upgrade or uninstall then can't overwrite/remove the binary and
fails ("file in use" / reboot required) — the Restart Manager doesn't reliably
catch a no-window, DETACHED_PROCESS daemon in its own process group.
- spawn: extract the "stop the running daemon" half of `restart()` into a
reusable `stop()` (Shutdown -> await exit -> pid reap fallback -> clear
endpoint); `restart()` is now `stop()` + `ensure_running()`.
- main: add a `--stop-daemon` CLI entry that runs `stop()` and returns before
any GUI init, so it never opens a window.
- installer: in PrepareToInstall, extract the *new* tty7.exe to {tmp} and run
`--stop-daemon` (the new binary understands the flag; an old installed one
would launch the GUI instead), releasing the lock before file copy. Mirror it
in [UninstallRun]. Keep CloseApplications as a backstop but RestartApplications=no
(the GUI respawns the daemon on next start).

bundle-windows.ps1 now compiles windows-installer.iss (ISCC is preinstalled
on windows-latest) from the same staged payload as the zip, producing
tty7-<version>-windows-x86_64-setup.exe: per-user install by default with an
all-users option, Start Menu shortcut, Apps uninstall entry, optional desktop
icon. Release workflow uploads the new artifact; READMEs and CHANGELOG updated.
