refactor(i18n): align analysis with Vite environment graphs

[hyoban]

Summary

Fixes #42655

The i18n analyzer could read disk modules that differed from Vite’s runtime imports. Analyze completed client, SSR and RSC graphs using environment-specific resolution, preserve query/JSON module identities, and block stale disk fallback after changed or untraceable imports. Connect environments only through explicit RSC client references.

Keep namespace inference limited to literals, inline arrays and immutable string constants. Runtime parameters, function results and bound arrays remain unknown. Expose an adapters option for custom translation APIs (source module, export name, namespace/selector argument indexes and optional private forwarding functions). Keep Dify registrations in vite.config.ts; the plugin only hardcodes official API names. Analyze registered calls through aliases/re-exports and verify Dify forwarding contracts against the actual wrappers. Dynamic adapter arguments remain unknown. Retain TypeScript selector/key matching and conservative dynamic-key protection; external dependencies and generated resource helpers are analysis boundaries rather than individual warnings.

Print a compact build summary and write full route groups, source evidence and shared dependency paths to i18n-routes.json. Signin validates detected namespace usage; rejecting unknown namespaces remains opt-in. This is a static estimate, not proof of complete runtime coverage, and does not change translation loading.

Make 12 finite business translation calls statically visible and remove five obsolete explore keys from all 25 locales. Reuse catalog indexes and identical multi-format analysis only within the current build.

Screenshots

No visual changes. Console output now shows counts and the report path instead of listing every route.

Validation

• 105 analyzer tests, 5 adapter contract tests and 23 server translation tests pass. The preceding final review also passed 119 related component/hook tests. Coverage includes environment isolation, repeated builds, multi-format reuse, rewritten/virtual/external imports, query/JSON modules, strict validation and compact console output with detailed JSON retained.
• Repository-wide pnpm exec vp run -w check and pnpm exec vp staged pass.
• Full pnpm run build:vinext passes, including standalone packaging; no additional unused keys.
• Production report: 110 routes, 2 unknown-namespace records from the runtime route Provider, 6 dynamic-key records protecting permissionKeys, and 0 unresolved application import warnings. The shared runtime Provider remains an unknown source on all routes; opaque dependencies are intentionally outside warning scope.

Checklist

• This change requires a documentation update, included: Dify Document (not required; internal plugin README updated)
• I understand that this PR may be closed in case there was no previous discussion or issues. (This doesn't apply to typos!)
• I've verified the change and added or updated tests where meaningful regression risk justifies coverage.
• I've updated the documentation accordingly.
• I ran vp staged (frontend); backend checks are not applicable.
