- refine dependency features and versions in Cargo.toml files
- switch from parking_lot to std sync primitives
- remove dashmap dependency and use DefaultKeyedStateStore
- update crates
Replace parking_lot with std::sync::{Mutex, RwLock, Condvar} throughout the
codebase. Update dependencies and code to use poisoning-aware locks, adding
explicit panic messages where necessary. Update governor to use DashMapStateStore
for rate limiting.
