The standalone GameCult/cultcache-rs repo is being retired; CultLib
(packages/cultcache-rs) is the only canonical Rust CultCache implementation.
brokkr-daemon still depended on the local standalone clone via a relative
path, which meant that repo had to keep existing just for Brokkr to build.
Switch to the same pinned-git-dependency pattern CodexConnector already uses,
pointing at CultLib's package by name and pinning to CultLib origin/main
(c2a9a6e5). No source changes were needed: CultLib's cultcache-rs exposes the
same CacheBackingStore/CultCacheEnvelope/SingleFileMessagePackBackingStore API
Brokkr already uses, with identical field names and signatures.
Cargo.lock gains redb 4.2.0 and windows-sys 0.59 as new transitive dependencies of CultLib cultcache-rs; they are not version bumps, and Brokkr never opens a redb store.
