docs(windows): the setup program is a real install route, so describe it (#1202)

[gen16k]

What this is about

WairedSetup-<version>-x64.exe is attached to every release and every edge
prerelease, and it is a full install path: it elevates, registers the service,
starts it, and turns on the Claude Code integration by default. docs.waired.ai
described one route — the iwr … | iex line — and until #1199 did not name the
setup program anywhere on the site.

Two things had already gone wrong because of that gap:

• packaging/windows/ sat outside scripts/ci/docs-surface-guard.sh's surface
  list until installer/windows: the GUI installer does not report success when it installed nothing (#1181) #1199 added it, so the GUI installer's behaviour could change with
  no docs page obliged to keep up. That is how
  getting-started/update.mdx came to promise "A fresh install behaves the
  same way: it stops rather than leaving a computer with programs that cannot
  run" — true of install.ps1, not of the GUI installer, which is WairedSetup: the GUI installer reports success and enables the Claude Code integration although the agent service was never installed — leaving Claude Code broken #1181.
• Every release's notes say the setup program is "unsigned -- see SmartScreen
  note in docs" (.github/workflows/release.yml:207). There was no SmartScreen
  note in docs; SmartScreen appeared nowhere under docs-site/.

Fixes #1202
Refs #1181, #1199, waired-ai/waired#1312 (L96)

What the section says

One new section, ## Install with the setup program, between "Read the script
before running it" and "Skip the inference engine" — in the order a person
downloading it actually meets things:

• where to get it, and why there is no latest/download/… shortcut (the
  filename carries the version);
• Windows protected your PC and the way through it (More info → Run
  anyway), and that the PowerShell line does not raise it — which is why the
  page still leads with that;
• the permission prompt, for the reason already given above it on the page;
• the wizard: it never asks where to install (-InstallDir is the PowerShell
  route's), and has one checkbox, under Claude Code integration:;
• that it does not run waired init, so signing in is still ahead of you,
  plus the finish-page checkbox and the two Start Menu entries;
• the log it always writes (SetupLogging=yes since installer/windows: the GUI installer does not report success when it installed nothing (#1181) #1199) — what you attach to
  a bug report;
• in-place upgrade, and uninstall via Settings, including that
  %ProgramData%\waired is kept by default so a reinstall re-uses the device
  key;
• the unattended switches, with exit 0 / exit 7, linking to the refusal
  section installer/windows: the GUI installer does not report success when it installed nothing (#1181) #1199 added.

The opening line moves from "Installing is one command." to "Installing is one
command — or a setup program you double-click", so the page does not contradict
its own new section.

The checkbox is described, not quoted. Its on-screen text still says the
integration "transparently falls back to the real Anthropic API", and #1198 is
retiring exactly that behaviour. Quoting it here would go stale the day that
lands; the repo rule is that a wording fix changes the product string and its
docs together, so this page does not pin a string that is already moving.

Also: the "What gets installed" table listed Waired as the only Start Menu
entry. Both installers create Waired and Waired (CLI)
(waired-setup.iss [Icons], install.ps1 New-StartMenuShortcuts), so the
row now says both.

Verification

• Every fact checked against packaging/windows/waired-setup.iss
  (DisableDirPage=yes, SetupLogging=yes, the claudeproxy task and its
  group label, the finish-page description, exit 7 from PrepareToInstall, the
  uninstall prompt defaulting to No, UninstallSilent keeping state) and
  packaging/windows/README.md §"Code signing (deferred)" for the SmartScreen
  wording.
• npm run i18n:check: 32 pairs, all in sync; the ja mirror keeps the same
  headings and fenced blocks.
• astro build was not run locally (no node_modules in this checkout); the
  docs-site build job on this PR is the check.

Not in scope

Screenshots of the wizard, and a page of its own. If the setup program becomes
a route we recommend rather than tolerate, that is the moment for both — and it
is gated on signing (waired#759), which is also what would remove the
SmartScreen paragraph.
