/**
* Local-filesystem implementation of the `ctx.fs` provider seam.
* {@link LocalFileSystem} subclasses {@link FileSystem} and backs the eight
* text-storage primitives with the host filesystem via
* {@link module:@deepseek-ai/dsh-fs-local/fsio}. Path resolution uses
* `realpath`, so the stable `targetKey` is the real file identity (two input
* paths reaching the same file through symlinks share one key, and writes land
* on the link target — preserving the link).
*
* Future sandboxed/remote/virtual backends are sibling packages implementing
* the same interface; loading this one populates `ctx.fs`.
*
* Host-filesystem implementation of `ctx.fs`. Realpath-derived target identity makes aliases
* share stale guards, and writes through a symlink update its target without replacing the link.
* @module @deepseek-ai/dsh-fs-local
