fix(proxy): disable proxying for static deployments (1.x backport)

[harlan-zw]

🔗 Linked issue

Resolves #875
Backport of #876

📚 Description

A nuxi generate site has no Nitro server to answer /_scripts/p/**. The module still rewrote bundled scripts to those URLs, so beacons hit <domain>/_scripts/p/cloudflareinsights.com/cdn-cgi/rum and static hosting answered 405. The existing static warning only read NITRO_PRESET, which nuxi generate never sets, so the breakage shipped silent.

Static output is now detected from _generate, nitro.static, and the static Nitro presets. Proxy rewrites, the intercept plugin, auto-injected proxy endpoints, URL signing, and the proxy route are skipped, and one warning lists the affected scripts. Scripts still bundle and load from your own domain. Collection requests keep their original third-party URLs and go direct, which is what Cloudflare Web Analytics needs on static hosting.

Checked by hand on the 1.x playground, since CI does not inspect generated assets:

• nuxi generate: the bundled beacon (_scripts/assets/e1ac4849b9d4a498.js) has zero /_scripts/p references and keeps the direct cdn-cgi/rum endpoint, so the 405 from Cloudflare Web Analytics in SSR:false #875 is gone
• nuxi generate prints the new warning listing every affected script, including the proxy URL signing note
• nuxi build (server runtime): proxy config still lands in the Nitro server bundle (nuxt-scripts-proxy, signing intact) and the beacon is still rewritten to /_scripts/p

📝 Walkthrough

Walkthrough

Nuxt Scripts now detects static output from generation flags, Nitro settings, and normalized preset names. It skips proxy handlers and proxy integrations for static targets. It records affected scripts and emits a build warning. Collection requests use direct third-party URLs. Unit tests cover detection and normalization. Documentation describes this behavior and recommends Nitro server output when proxying is required.

Estimated code review effort: 3 (Moderate) | ~20 minutes

- Around line 239-243: Update the URL-signing section to align with the static
deployment behavior described above: clarify that nuxt generate and other static
output emit neither proxy routes nor proxy URLs, and remove wording that treats
proxy endpoints as present in generated pages. Preserve the server-rendered
Nitro behavior and any URL-signing guidance that remains applicable there.

In `@packages/script/src/module.ts`:
- Around line 789-795: The signing branch currently uses a separate incomplete
static-target check, so update it to reuse the computed staticProxyTarget
predicate for all server-dependent setup. Ensure static targets including
_generate, nitro.static, SERVER_PRESET=gitlab-pages, and vercelStatic skip
secret resolution and proxy-token.server registration, while preserving
azure-static and firebase-static in the shared preset handling.
