Adopt Rolldown hook filters for statically-checkable plugin hooks

[Copilot]

This PR applies Rolldown/Vite hook filters to plugin hooks that were already gated by static id checks, reducing unnecessary hook invocations while preserving existing behavior. It focuses on hooks where matching can be determined upfront from request shape.

• Scope of filter adoption

  • Converted eligible resolveId, load, and transform hooks to object-hook form ({ filter, handler }) in:
    • packages/pages/src/pages.ts
    • packages/images/src/images.ts
    • packages/mdx/src/mdx-vite-plugins.ts
    • packages/iles/src/node/plugin/plugin.ts
    • packages/iles/src/node/plugin/documents.ts

• Behavior-preserving details

  • Kept virtual routes handling compatible with prefixed module IDs (e.g. \0, /@id/) in pages hooks.
  • Removed redundant in-handler guards where filter matching already guarantees hook eligibility.
  • Left non-static/behavior-sensitive paths unchanged (notably in islands entrypoint resolution/loading) where filtering was not safely equivalent.

• Representative pattern applied

  transform: {
    filter: { id: /vue&type=page/ },
    async handler (_code, _id) {
      return 'export default {};'
    },
  }
