Fix `bun run dev:desktop` from not terminating properly on SIGINT/SIG…

…TERM/SIGHUP (pingdotgg#305)

* fix: handle turbo shutdown in dev runner

* refactor: rely on effect child process shutdown

* refactor: inline turbo shutdown timeout

* add back sigint sigterm sighup handling

* refactor: tighten turbo signal forwarding

* refactor: inline dev runner errors

* fix: use detached false instead of manual signal forwarding

Effect defaults to detached: true on non-Windows, putting turbo in a
new process group where terminal signals (Ctrl+C) never reach it.
Setting detached: false keeps turbo in the same group, eliminating
the need for ~130 lines of manual signal forwarding.

* Update scripts/dev-runner.ts

Handle prerelease tags in GitHub release publishing (pingdotgg#344)

* Handle prerelease tags when publishing GitHub releases

- Derive `is_prerelease` and `make_latest` from the version format in preflight
- Mark suffixed versions (for example `1.2.3-alpha.1`) as prereleases
- Keep only plain `X.Y.Z` releases marked as latest
- Document prerelease/latest behavior in `docs/release.md`

* Force desktop auto-updates to stable latest channel

- set Electron updater channel to `latest`
- disable prerelease and downgrade updates regardless of app version

Fix CLI publish using stale package.json version

The publish_cli job was checking out the default ref instead of the
preflight commit, so it published with the pre-bump version. Add the
correct ref to checkout and a --app-version flag as a safety override.

Fix electron-updater auth for private GitHub repos

Use setFeedURL with private: true when a GitHub token is provided so
electron-updater queries the GitHub API instead of the public Atom feed
which rejects Bearer auth headers.
