#10894: Docs: fix legacy branding, add config reference, expand cron troubleshooting

## Summary - **Fix legacy branding**: rename "Clawdbot" → "OpenClaw" in all 3 GitHub issue templates (bug report, feature request, contact links) - **Add configuration reference**: new `docs/gateway/configuration-reference.md` with all 200+ config fields organized by group, sourced from `src/config/schema.ts` field labels and help text - **Expand cron troubleshooting**: from 2 items to 6 — covers timer drift, stuck jobs, delivery failures, and legacy migration (addresses recurring issues from #10776, #9733, #9823, #9948, #9932) - **Clarify CLI command relationships**: add cross-linked callout boxes for `config` vs `configure` and `node` vs `nodes` - **Add architecture overview**: AGENTS.md/CLAUDE.md now includes a data flow diagram and subsystem map for onboarding new contributors ## Test plan - [ ] Verify issue templates render correctly on GitHub (new issue page) - [ ] Verify `docs/gateway/configuration-reference.md` renders in Mintlify (`pnpm docs:dev`) - [ ] Verify nav link appears under "Configuration and operations" in docs sidebar - [ ] Verify cron troubleshooting section renders with correct anchors - [ ] Verify CLI doc callout boxes render and cross-links resolve 🤖 Generated with [Claude Code](https://claude.ai/claude-code) <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> - Updates GitHub issue templates to use "OpenClaw" branding instead of legacy naming. - Expands `docs/automation/cron-jobs.md` troubleshooting guidance with additional common failure modes. - Adds cross-links/callouts clarifying related CLI commands (`config` vs `configure`, `node` vs `nodes`). - Extends docs navigation (`docs/docs.json`) and adds a new gateway configuration reference page listing schema fields. - Adds an architecture overview section to `AGENTS.md` to help onboard contributors. <h3>Confidence Score: 3/5</h3> - Mostly safe to merge, but there are a couple of docs correctness issues that will mislead readers if not fixed. - Changes are documentation-only and scoped, but there are concrete correctness problems: `AGENTS.md` is mislabeled as `CLAUDE.md`, and the new configuration reference points to a likely wrong config file path/format. These should be corrected to avoid ongoing confusion and support burden. - AGENTS.md; docs/gateway/configuration-reference.md; docs/cli/configure.md <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
