fix: remove unused type alias and fix test compatibility with Bun 1.3.11

- Remove unused ParsedChunkTarget type alias (lint error)
- Increase setImmediate timing in history storage compat test
- Mock warmPythonEnvironment in python tool tests
- Fix tlaplus LSP test to spy on $which instead of Bun.which
