test: add bats test suite for lib/ helper scripts

110 tests across 10 test files covering all lib/ scripts:
- archeflow-event.sh: JSONL format, seq numbering, parent fields, validation
- archeflow-memory.sh: add/list/decay/forget/inject/extract commands
- archeflow-git.sh: branch creation, commit format, merge strategies, safety
- archeflow-report.sh: markdown output, summary mode, in-progress handling
- archeflow-progress.sh: progress.md generation, JSON mode, error handling
- archeflow-score.sh: archetype scoring, effectiveness report, validation
- archeflow-dag.sh: DAG rendering, color flags, tree structure
- archeflow-rollback.sh: arg parsing, phase validation, mutual exclusivity
- archeflow-init.sh: template listing, clone from project, arg validation
- archeflow-review.sh: diff modes, stats, branch/commit range review

Includes test_helper.bash (shared setup/teardown with temp git repos)
and scripts/run-tests.sh runner.
