* Precompute install-audience flag for the hero switcher
The home hero's "For humans / For agents" tab was tracked in React
state, so every reload snapped back to the default tab and broke the
"page is static without layout shift" promise. Model it as a
precomputed flag like the other hero flags:
- Add `installAudienceFlag` (`'humans' | 'agents'`, cookie key
`install-audience`, default `'agents'`) and include it in
`rootFlags` so `generatePermutations` covers both variants
- Read the flag on the server and publish it via `FlagValues`
- New `InstallCommand` client wrapper renders `CommandPromptRoot`
with the server value and, on click, writes the cookie + calls
`router.refresh()` (optimistic override pattern mirroring
`FlagToggle`)
Result: the proxy's `precompute(rootFlags)` reads the cookie, rewrites
to the matching `[code]`, and SSR renders the correct tab from the
start — reloads stay on the user's choice with no client-only state.
