TypeDoc generates an insanely large 16GB output on a pnpm monorepo with lots of packages

Expected Behavior

To produce a small output

Actual Behavior

The TypeDoc output is large, all inter-package dependencies are duplicated in the individual package output folders.

I don't remember this being a problem in earlier versions, I've been using "entryPointStrategy": "packages" for a while now. Also do note that while "node_modules/**" is not part of the "exclude" array, I did try it and made no difference.

The ncdu output might give a better idea, each dependency and their dependencies are present in every media folder. Each of these dependencies are part of this repository.

Steps to reproduce the bug

Given the nature of the problem I can only provide a large repo as example

npm i -g pnpm
git clone -b typedoc https://github.com/AlexAegis/js-tooling
pnpm i
pnpm typedoc_

Then check the size of .cache/typedoc

Environment

• Typedoc version: 0.26.2
• TypeScript version: 5.5.2
• Node.js version: v20.14.0
• OS: arch

The cause of this is your readme:

## config providers

These packages only contain configurations, that could be independently used

- [commitlint-config](packages/commitlint-config/)
- [eslint-config-core](packages/eslint-config-core/)
- [eslint-config-vitest](packages/eslint-config-vitest/)
- [lint-staged-config](packages/lint-staged-config/)
- [prettier-config](packages/prettier-config/)
- [remark-preset](packages/remark-preset/)
- [standard-version](packages/standard-version/)
- [stylelint-config](packages/stylelint-config/)
- [ts](packages/ts/)
- [turbowatch](packages/turbowatch/)
- [vite](packages/vite/)
- [vitest](packages/vitest/)

TypeDoc is seeing those relative links and deciding that they mean it ought to copy those directories to your documentation site. I didn't intend for relative link copying to include directories. With a patch to ignore directories, the generated site is back down to 2.1mb.
