fix: resolve compilation error and warnings in Rust backend (#95)

* fix: resolve compilation error and warnings in Rust backend

- Fix syntax error in directive.rs phase_replanning (bad merge created
  duplicate code blocks with broken `.await {` syntax)
- Remove unused imports: WorktreeError, DaemonReauthStatus, ratatui::prelude
- Prefix unused variables with underscore: claude_command, content, owner_id
- Suppress unused_assignments warning on final_exit_code
- Add #[allow(unused_imports)] for cfg(unix) CommandExt imports

* WIP: heartbeat checkpoint

* fix: suppress remaining compiler warnings for clean build

- Add #[allow(dead_code)] for unused but intentionally kept functions
- Remove useless self-assignments in listen handler
- Fixes: truncate_string, checkout_commit, handle_get_worktree_diff,
  default_max_retries, STREAM_CHUNK_MS, listen(), MessageResponse.role
