tlc: cleanup — remove dead code, debug logging, fix import placement

- Remove two dead pub fn render free functions (render.rs + mod.rs)
- Remove debug_raw_event/should_log_raw_event (always-on /tmp logging)
- Move use std::sync::Arc to top of dispatch.rs
- Fix unused imports from dead code removal
