Module kernel 

The Kernel (核) — the heart of kaish.

The Kernel owns and coordinates all core components:

• Interpreter state (scope, $?)
• Tool registry (builtins, user tools)
• VFS router (mount points)
• Job manager (background jobs)

Structs

ExecuteOptions

Per-call options for Kernel::execute_with_options.

Kernel

The Kernel (核) — executes kaish code.

KernelConfig

Configuration for kernel initialization.

OverlayHandle

Handle to an active overlay session, kept on the kernel and shared to ExecContext so the kaish-vfs builtin can reach the OverlayFs.

Enums

VfsMountMode

VFS mount mode determines how the local filesystem is exposed.
