Strip Zo Computer references, rename cascade-cheap to cascade, real BYOK init flow.
optimus init manual/optimus init autonow actually configure BYOK provider keys (previously misrouted to the wiki project scaffold). Keys are stored in~/.optimus/config.tomlunder[secrets](0600), env vars always take priority.- Fixed an audit-chain bug where a nanosecond-derived ID could collide under fast repeated writes on hosts with coarse clock resolution, silently corrupting the hash chain.
- Switched TLS root store to the OS/enterprise trust store (
rustls-tls-native-roots) instead of a bundled CDLA-licensed cert list. - crates.io publishing prep: internal path deps now carry version constraints, cargo-deny clean.
