fix(rocket): support dependencies in linked installs

[BeWoFinum]

Summary

Fix Rocket dependency and browser asset resolution when Rocket is installed as a linked or nested package.

Previously, several parts of Rocket relied on dependencies being hoisted into the Site Author project. This worked with some npm layouts but failed when Rocket was linked from another directory.

Changes

• Route generated Markdown SSR imports through @rocket/js/ssr.js.
• Re-export Lit’s html and SSR render from Rocket.
• Resolve Rocket-owned icon packages relative to Rocket when unavailable from the Site Author project.
• Generate Web Dev Server outside-root URLs for assets from linked packages.
• Prefer browser packages installed in the Site Author project to avoid loading duplicate custom-element packages.
• Resolve shared packages using browser, import, and module conditions:
  • @floating-ui/dom now uses its ESM entry.
  • nanoid now uses its browser entry instead of importing node:crypto.
• Fall back to Rocket’s dependencies when the Site Author does not provide a package.
• Add a patch changeset.

Why

Depending on npm hoisting caused different behavior between regular and linked installations.

Generated modules could require consumers to install Rocket’s transitive dependencies, linked assets returned 404 responses, and duplicate Web Awesome installations attempted to register the same custom elements.

The updated resolution behavior works independently of npm’s physical dependency layout.

Verification

• Added regression tests for:
  • Generated Markdown SSR imports
  • Rocket-owned icon packages
  • Linked outside-root assets
  • Project package preference
  • Missing-package fallback
  • ESM export conditions
  • Browser export conditions
  • Node built-in exclusion
• 35 focused tests pass.
• Type checking passes.
• ESLint and Prettier pass.
• Tested against Finum using file:../rocket.
• Verified the generated Rocket, Lit, Web Awesome, Floating UI, Nano ID, CSS, SVG, and hydration URLs return HTTP 200.
