json-language-service browser bundle includes TypeScript runtime

[shahabdsh]

Summary

@player-tools/json-language-service browser bundling currently includes TypeScript compiler runtime, even though validation/LSP should operate on XLR only and should not need TS at this layer.

Repro

Bundle language/json-language-service/src/index.ts for browser (esbuild) and inspect output for TS runtime markers.

Example markers currently present:

• /typescript/lib/typescript.js
• getDefaultLibFileName
• Compiler_option_0_of_value_1_is_unstable

Expected

Browser bundle for json-language-service excludes TypeScript runtime.

Actual

TypeScript runtime is bundled via @player-tools/xlr-sdk dependency chain.

Repro branch pushed for easier validation:

• Branch: repro/lsp-bundles-typescript
• URL: https://github.com/shahabdsh/player-ui-tools/tree/repro/lsp-bundles-typescript
• Commit: 41cfb59

Run:
pnpm vitest language/json-language-service/src/__tests__/bundle-hygiene.test.ts

Expected result on this branch: test fails because browser bundle contains TS runtime markers.

Closing in favor of player-ui/xlr#7, which now has the canonical repro branch and up-to-date details.
