fix: add missing Rust imports for Windows build and check in pending changes

Add `use std::hash::{DefaultHasher, Hash, Hasher}` behind #[cfg(windows)]
in runtime_manager.rs — these types are used in hash_seed() which only
compiles on Windows, causing CI failure.

Also includes: app component refactors (agent-list, agent-status-bar,
stream-strategy-web), website index updates, server dep additions
(fast-uri, rotating-file-stream sort), lockfile sync, and removal of
RUNTIME_SIMPLIFICATION_PLAN.md.
