fix: declare optional peer types

[cyphercodes]

Summary

Adds the bundler/runtime packages referenced by unplugin's generated declaration files as optional peer dependencies, including the existing Bun type package.

This lets strict package managers surface the optional type packages instead of leaving consumers with unresolved imports from dist/index.d.mts.

Fixes #605

Test plan

• pnpm run typecheck
• pnpm run lint
• pnpm test
• git diff --check

Summary by CodeRabbit

• Chores
  • Updated package dependency declarations to treat several build-tool libraries as optional peer dependencies.
  • Adjusted development tooling sourcing for type support and bundling to align with the updated optional peer dependency strategy.
  • Reorganized the workspace dependency catalog so optional vs. required relationships are reflected more accurately.
  • Updated the type-check configuration to ignore an unused warning for one type-support package.

📝 Walkthrough

Walkthrough

Updated dependency configurations to mark build tool types as optional peer dependencies. peerDependenciesMeta in package.json declares build tool peers as optional, bun-types-no-globals and esbuild are relocated from the dev catalog to the peer catalog in pnpm-workspace.yaml, and tsdown configuration excludes bun-types-no-globals from unused checks.

Changes

Optional Peer Dependencies for Build Tools

Layer / File(s)	Summary
Declare optional peer dependencies in package.json package.json	peerDependencies and peerDependenciesMeta entries mark @farmfe/core, @rspack/core, bun-types-no-globals, esbuild, rolldown, rollup, unloader, vite, and webpack as optional. devDependencies and esbuild resolutions for bun-types-no-globals and esbuild are updated to reference catalog:peer instead of catalog:dev.
Reorganize pnpm catalog structure pnpm-workspace.yaml	bun-types-no-globals and esbuild are relocated within catalogs.dev.peer from their earlier position before eslint to immediately before rolldown.
Configure tsdown to ignore optional peer types tsdown.config.ts	bun-types-no-globals is added to the unused.ignore list to exclude it from unused-check warnings.

Poem

🐰 Hopping through dependencies with care so deep,
Build tool types now marked as optional peer,
No stricter resolver's frown will make us weep,
Types cascade down when dev deps appear,
A cleaner config makes the vision clear! 🔧

Pushed a focused follow-up for the CI failures after the base merge:

• removed duplicate unused dev catalog entries for bun-types-no-globals / esbuild
• ignored bun-types-no-globals in unplugin-unused since it is an optional type-only peer package

Verified locally:

• pnpm install --frozen-lockfile --ignore-scripts
• pnpm run build
• pnpm run typecheck
• pnpm run lint
• pnpm run test
• git diff --check
