Implements IEnvironmentCheck for the four checks derivable without a
Claude CLI probe:
- GitCheck (Error) - resolves git via ExecutableResolver (handles .cmd
shims), parses `git --version`.
- GitIdentityCheck (Warning) - user.name/user.email presence; Unknown
(not Failed) if git itself is missing, so it doesn't duplicate GitCheck's
failure.
- PortCheck (Warning) - loopback bind probe for SignalRPort/ExternalMcpPort;
resolves the owning process via a new NetstatPortOwnerResolver and treats
a port held by the running ClaudeDo.Worker (update/repair case) as Ok.
Both ports are configurable, hence a warning.
- WriteAccessCheck (Error) - create+delete a probe file in InstallDirectory
and ~/.todo-app (walking up to the first existing parent), not an ACL
read (ACLs lie on virtualized paths).
Process calls go through a new IProcessRunner wrapping the existing static
ProcessRunner, so checks are fakeable in tests instead of spawning real
processes.
DotnetRuntimeCheck was intentionally not added: per
docs/explore-notes/installer-preflight.md, App/Worker publish
self-contained (no preinstalled runtime needed), and the Installer's own
.NET 8 Desktop Runtime requirement is self-proving - a framework-dependent
apphost can't reach managed code at all if that runtime is missing, so a
check running from inside the process can never observe a failure.
Brings in two prerequisite commits this task builds on that hadn't reached
this branch yet: the IEnvironmentCheck/EnvironmentCheckService scaffolding
and the installer-preflight.md research note.
Scaffolding for environment checks: IEnvironmentCheck, CheckResult/
CheckSeverity/CheckStatus, and EnvironmentCheckService that runs checks
in parallel while preserving input order, never throws (a failing
check becomes Unknown), and reports HasBlockingError only for
Error+Failed.
Every update failed at "Could not replace the existing files": the app
relaunches the installer via ShellExecute without a working directory, so
it inherited the app's CWD - which the Start Menu shortcut sets to
<InstallDir>\app. A process's current directory is locked by Windows, so
the installer blocked its own `app` -> `app.bak` rename. Retries and
reboots could not help.
- installer moves its CWD to %TEMP% at startup, and both relaunch sites
in the UI pass an explicit WorkingDirectory
- cache the release zip in %TEMP%\ClaudeDo-download-cache and reuse it on
a retry while its SHA-256 still matches, so a failed attempt no longer
costs another full download; drop it after a successful install, delete
a mismatching one, prune zips of other versions
- roll back a half-done stash: a leftover app.bak was deleted as a stale
stash on the next attempt, and that copy was the only one left
- name the blocked path in the error message
Replaces schtasks /Create with AutostartShortcut.Install; migrates away
legacy scheduled task and Windows service on upgrade. Removes ScheduledTaskXml.

A LocalSystem Windows service can't see the logged-in user's Claude CLI
authentication, so the worker now runs as the current user via a hidden
per-user logon Scheduled Task with restart-on-failure.
- Worker is WinExe (no console window) with a Serilog rolling file sink and
a single-instance mutex so the logon task, app ensure-running, and Restart
button can't fight over the SignalR port.
- Installer replaces the service steps (register/start/stop) with autostart
task steps, migrates the legacy ClaudeDoWorker service away on update, and
removes the task on uninstall. ServicePage drops the service-account UI.
- UI gains a WorkerLocator; the app ensures the worker is running at startup
and the Restart button kills+relaunches this install's worker process.

The release workflow runs on a Linux container; building net8.0-windows +
UseWPF=true requires this opt-in property since .NET 8. No-op on Windows.

Placeholder edit to App.xaml.cs to keep the project building until Task 11
wires the new async detector.
