fix: resolve @codemirror/lsp-client from git submodule

[RohitKushvaha01]

• setup initializes the submodule before installing dependencies
• CI checkout steps that install or build fetch submodules recursively
• rspack treats the submodule's prebuilt dist as a dependency, not as first-party source
• docs clone with --recurse-submodules and note the setup fallback

Summary

This PR moves @codemirror/lsp-client from a remote Git dependency to a pinned repository submodule and updates setup, CI, bundling, lockfiles, tests, and contributor documentation accordingly.

• CI and nightly builds now check out submodules recursively.
• Setup validates submodule contents before dependency installation.
• Rspack treats the linked submodule’s prebuilt output as dependency code.
• The latest revision strengthens partial-checkout validation and adds corresponding tests.
