Copy an existing target's DACL onto the empty staging file before any content is written, then publish with ReplaceFileW so Windows replacement keeps the target security descriptor instead of inheriting the broader parent policy.
Keep new-file inheritance and POSIX mode behavior unchanged, retain the already-protected temp when a concurrently removed target requires rename fallback, and translate native errors into Node-style codes for the filesystem error boundary.
Add host-independent Win32 binding coverage, native Windows descriptor assertions, package documentation, and a bilingual implemented RFC that supersedes the earlier inheritance-only replacement claim.
Adapt the four fs packages to master's single-tsconfig build convention
(lib/types outDir + types path + files allowlist), brought in by the merge.
While doing so, drop dsh-tool-fs's /read//write//edit subpath plugins. They
were the only subpath-export package in the tree and forced bespoke tsdown,
tsconfig path, package.json files, and workspace-constraint handling that no
sibling tool package (e.g. dsh-tool-bash) carries, for a focused-deployment
use case no consumer needed. dsh-tool-fs is now a single root plugin that
registers read/write/edit, mirroring dsh-tool-bash; the per-tool registration
helpers stay internal modules the root composes. The file-context event-gate
RFC is amended to record the narrowed scope.
