Crate kaish_kernel 

kaish-kernel (核): The core of 会sh.

This crate provides:

• Lexer: Tokenizes kaish source code using logos
• Parser: Builds AST from tokens using chumsky
• AST: Type definitions for the abstract syntax tree
• Interpreter: Expression evaluation, scopes, and the $? result type
• VFS: Virtual filesystem with mount points
• Tools: Tool trait, registry, and builtin commands
• Scheduler: Pipeline execution and background job management
• Paths: XDG-compliant path helpers
