refactor(hooks): improve interactive bash session tracking and command parsing

- Replace regex-based session extraction with quote-aware tokenizer
- Add proper tmux global options handling (-L, -S, -f, -c, -T)
- Add normalizeSessionName to strip :window and .pane suffixes
- Add findSubcommand for proper subcommand detection
- Add early error output return to avoid false state tracking
- Fix tool-output-truncator to exclude grep/Grep from generic truncation
- Fix todo-continuation-enforcer to clear reminded state on assistant response
- Add proper parallel stdout/stderr reading in interactive_bash tool
- Improve error handling with proper exit code checking
