fix(read-lifecycle): persist STALE Read originals in the CCR store

Browse source 
ContentRouter.transform instantiated ReadLifecycleManager with
compression_store=kwargs.get("compression_store"), but no caller ever
sets that kwarg. self.store was therefore always None, so STALE/SUPERSEDED
Read markers were emitted with a SHA-256 hash but the original content
was never stored — headroom_retrieve(hash) 404'd on every Read marker,
breaking the CCR contract for the common Claude Code flow (read a file,
edit it, then want the prior content back).

Fall back to get_compression_store() when no store is explicitly injected,
matching how SmartCrusher, Kompress, and the search/log/diff/code
compressors already resolve theirs. The kwargs injection point is kept so
explicit overrides still work.
