feat: lightweight bootstrap context mode for heartbeat/cron runs (openclaw#26064) thanks @jose-velez

Verified:
- pnpm build
- pnpm check (fails on pre-existing unrelated repo issues in extensions/diffs and src/agents/tools/nodes-tool.test.ts)
- pnpm vitest run src/agents/bootstrap-files.test.ts src/infra/heartbeat-runner.model-override.test.ts src/cli/cron-cli.test.ts
- pnpm test:macmini (fails on pre-existing extensions/diffs import errors; touched suites pass)
