Implements the split-the-filesystem-seam RFC. ctx.fs shrinks to a text-storage provider seam (resolve/stat/readText/streamText/writeText/editText with branded FsTargetKey/FsVersion and an explicit FsWriteExpectation); the new dsh-file-context package owns the model-facing policy (read windowing, observed-state, write/edit freshness) as the concrete ctx.fileContext service. Authorization is now freshness-based rather than full/partial view: a windowed read records the file version and authorizes a later edit when the file is unchanged, removing the dead-end where reading lines 100-150 of a large file could not edit line 120. editText stays a provider primitive so version guard + literal match + atomic rewrite remain one critical section, and the stale check runs before matching so a stale edit reports FS_STALE_VERSION. tool-fs injects fileContext, never reaching around to ctx.fs (the no-bypass contract).
