fix: atomic review log helpers + platform-agnostic templates (v0.8.5) (#209)

* fix: add gstack-review-log and gstack-review-read atomic helpers

Branch names with `/` break review log filepaths when Claude Code runs
multi-line bash blocks as separate shell invocations. These two scripts
encapsulate the full operation in a single command.

* fix: replace multi-line eval+mkdir+echo blocks with atomic helpers

- Review log writes now use gstack-review-log (single command)
- Review dashboard reads now use gstack-review-read (single command)
- Remaining source+mkdir blocks use && chaining for variable persistence
- Regenerated all SKILL.md files

* fix: remove Rails-isms — platform-agnostic templates and checklist

- review/checklist.md: multi-framework examples (Rails/Node/Python/Django)
- plan-ceo-review: framework-agnostic grep + generic error table
- plan-eng-review: "corresponding test" not "JS or Rails test"
- CLAUDE.md: Platform-agnostic design principle + Testing section

* test: update tests for gstack-review-log/read helpers

- codex review log test: check for gstack-review-log instead of reviews.jsonl
- dashboard resolver tests: check for gstack-review instead of reviews.jsonl
