Module bun_shell 

Bun.Shell / Bun.$ — bridge to bun_shell_parser + bun_spawn.

Reuses bun_shell_parser::Lexer/Parser/AST for command parsing and bun_spawn::run for subprocess execution. No hand-written shell parsing or process management code.

Functions

install_bun_shell^⚠

Install Bun.Shell and Bun.$ on the global Bun object. Replaces the Phase 1 stub with a full implementation using bun_shell_parser + bun_spawn (SPEC: REQ-BAO-API-018 reuse mapping).
