Request for review: PR #493 in coc-tsserver (global plugin support + tsserver bridge)

[ChuYanLon]

Summary

PR neoclide/coc-tsserver#493 adds two features needed by Volar v3 and similar TypeScript-plugin-based extensions:

1. globalPlugins + pluginPaths in configure — plugins contributed via typescriptServerPlugins in package.json are now automatically loaded by tsserver globally.
2. typescript.tsserverRequest command — a bridge command that lets other extensions forward arbitrary tsserver commands through coc-tsserver's managed process.

Background

Volar v3 changes its architecture: instead of managing tsserver internally, it sends tsserver/request notifications from the Vue language server that must be forwarded to tsserver by the LSP client. The VS Code extension uses vscode.typescript-language-features's built-in typescript.tsserverRequest command. coc.nvim needs the equivalent.

Testing

Tested locally with @vue/language-server v3.3.4:

• LSP features (completion, hover, diagnostics, formatting) work
• Vue-specific TypeScript features (component names, props, directives) work via the bridge
• All contributed typescriptServerPlugins are loaded globally
