_Kerman 89321489db refactor(session-projection-cache): own the cache tree under a config root ...

Store each session's projection_cache.json under the cache's own root tree
(<root>/<session-id>/projection_cache.json, wired to dshHomePath('projections')
in the base bundle) instead of beside the session log via
sessionPersistence.locate(). The cache owns its directory layout, keys
directories by the code-generated session id, and never consults the
persistence layer; the service now injects only sessionProjections and
sessions.

Drop the coldSnapshot method and its readFrom-tail fold ladder: every cold
consumer refolds from the log itself, so the cache only serves the listing
read (cachedSnapshot, one async file read per session) and the write side.
Fail-soft durability, per-path write serialization, in-flight drain, and
atomic 0600 writes are unchanged; the chain cleanup now observes its own
rejection so a failed write cannot surface as an unhandled error.

dsh-session-persistence leaves peer/dev dependencies and the tsconfig
reference; dsh-atomic-write moves to peerDependencies. Config gains a
required root.
