Bundle extension (#1)

Introduces bundling to improve extension load time and bundle size. We now build two files from all dependencies: `extension.js`, containing the main body of the extension, and `proxy.js`, which houses the proxy language server. This results in a reduction in package size from 20MB to 1MB, and we ship only 13 files as opposed to roughly 3300 before this PR.

Due to quirks of esbuild and TypeScript, modules need to parse as "isolated" modules, meaning the global `types.ts` modules in use across the extension were no longer legal. These have been refactored to export their aliases and their uses are now explicitly imported.
