Add Random and Time effects for random number generation and
time-based operations. These effects can be used in any
effectful code block.
Random effect operations:
- Random.int(min, max) - random integer in range [min, max]
- Random.float() - random float in range [0.0, 1.0)
- Random.bool() - random boolean
Time effect operations:
- Time.now() - current Unix timestamp in milliseconds
- Time.sleep(ms) - sleep for specified milliseconds
Changes:
- Add rand crate dependency
- Add Random and Time effect definitions to types.rs
- Add effects to built-in effects list in typechecker
- Implement effect handlers in interpreter
- Add 4 new tests for Random and Time effects
- Add examples/random.lux demonstrating usage

Add a Language Server Protocol (LSP) server to enable IDE integration.
The server provides:
- Real-time diagnostics (parse errors and type errors)
- Basic hover information
- Keyword completions (fn, let, if, match, type, effect, etc.)
- Go-to-definition stub (ready for implementation)
Usage: lux --lsp
The LSP server can be integrated with any editor that supports LSP,
including VS Code, Neovim, Emacs, and others.
Dependencies added:
- lsp-server 0.7
- lsp-types 0.94
- serde with derive feature
- serde_json
