feat(tb-15rh): add tmux detector acceptance test execution script
Created bin/run-tmux-detector-acceptance.sh that runs the tmux
detector acceptance test 5 times with structured JSON output.
Features:
- Runs 5 iterations by default (configurable with -n)
- Captures per-run metrics: timestamp, pass/fail, duration, exit code
- Detects false positives and false negatives from logs
- Categorizes failure types (detection_timeout, unstuck_timeout, etc.)
- Outputs parseable JSON for analysis
- Command-line options: -n/--num-runs, -o/--output, -h/--help
Acceptance criteria met:
- Script executable at bin/run-tmux-detector-acceptance.sh
- Runs 5 iterations automatically
- Logs timestamp, pass/fail, execution time, error messages
- Outputs structured JSON format
- Manually tested and verified
