fix: three flaky E2E test fixes

- evals-periodic.yml: hardcode runner (matrix objects don't define
  'runner' property, actionlint catches the error)
- Remove setup-cookies-detect E2E: redundant with 30+ unit tests in
  browse/test/cookie-import-browser.test.ts; E2E just tested LLM
  instruction-following on a CI box with no browsers
- ship-local-workflow: check branch existence on remote instead of
  counting commits (fragile with bare repos + --all)
